Canine sexual dimorphism in Egyptian Eocene anthropoid primates: Catopithecus and Proteopithecus. (1/1158)

Two very small late Eocene anthropoid primates, Catopithecus browni and Proteopithecus sylviae, from Fayum, Egypt show evidence of substantial sexual dimorphism in canine teeth. The degree of dimorphism suggests that these early anthropoids lived in social groups with a polygynous mating system and intense male-male competition. Catopithecus and Proteopithecus are smaller in estimated body size than any living primates showing canine dimorphism. The origin of canine dimorphism and polygyny in anthropoids was not associated with the evolution of large body size.  (+info)

A modern human pattern of dental development in lower pleistocene hominids from Atapuerca-TD6 (Spain). (2/1158)

The study of life history evolution in hominids is crucial for the discernment of when and why humans have acquired our unique maturational pattern. Because the development of dentition is critically integrated into the life cycle in mammals, the determination of the time and pattern of dental development represents an appropriate method to infer changes in life history variables that occurred during hominid evolution. Here we present evidence derived from Lower Pleistocene human fossil remains recovered from the TD6 level (Aurora stratum) of the Gran Dolina site in the Sierra de Atapuerca, northern Spain. These hominids present a pattern of development similar to that of Homo sapiens, although some aspects (e.g., delayed M3 calcification) are not as derived as that of European populations and people of European origin. This evidence, taken together with the present knowledge of cranial capacity of these and other late Early Pleistocene hominids, supports the view that as early as 0.8 Ma at least one Homo species shared with modern humans a prolonged pattern of maturation.  (+info)

Comparison of cephalometric analysis using a non-radiographic sonic digitizer (DigiGraph Workstation) with conventional radiography. (3/1158)

Cephalometric analysis conventionally requires radiographic exposure which may not be compatible with the growing concern over radiation hazards. Recently, the Dolphin Workstation Imaging System introduced to the dental profession a non-radiographic system, called the DigiGraph Workstation which may be an alternative to cephalometric radiography. The aims of this study were to compare the validity and reproducibility of cephalometric measurements obtained from the DigiGraph Workstation with conventional cephalometric radiographs. The sample consisted of 30 human dry skulls. Two replicated sets of lateral cephalograms were obtained with steel ball markers placed at the majority of the cephalometric landmarks. Duplicate tracings prepared from each radiograph were digitized to obtain cephalometric measurements using the computer software, Dentofacial Planner. For the DigiGraph Workstation, double sonic digitizations were repeated twice for each skull, on two occasions. Fifteen angular and one linear measurements were obtained from both methods and these findings compared using ANOVA, paired t-tests and F-tests. All, except one, cephalometric measurement showed significant differences between the two methods (P < 0.0001). The DigiGraph Workstation consistently produced higher values in 11 measurements (mean differences +0.5 to +15.7 degrees or mm) and lower values in four measurements (mean differences -0.2 to -3.5 degrees). The standard deviations of the differences between readings of both methods were large (0.4-5.8 degrees or mm). The reproducibility of the DigiGraph Workstation measurements was lower than that of the radiographic measurements. The method error of the DigiGraph Workstation ranged from 7 to 70 per cent, while that of radiographic tracings was less than 2 per cent. It was concluded that measurements obtained with the DigiGraph Workstation should be interpreted with caution.  (+info)

Morphological changes in periodontal mechanoreceptors of mouse maxillary incisors after the experimental induction of anterior crossbite: a light and electron microscopic observation using immunohistochemistry for PGP 9.5. (4/1158)

Ruffini nerve endings (mechanoreceptors) in the periodontal ligament (PDL) of mouse incisors were examined to elucidate whether experimentally-induced crossbites cause any changes or abnormalities in their morphology and distribution. Anterior guiding planes were attached to the mandibular incisors of 3-week-old C3H/HeSlc mice. At 3 days and 1, 2, 4, 6, and 8 weeks post-attachment of the appliance, the mice were sacrificed by perfusion fixation. Frozen sagittal cryostat sections of the decalcified maxillary incisors were processed for immunohistochemistry of protein gene product 9.5, followed by histochemical determination of tartrate-resistant acid phosphatase activity to reveal sites of alveolar bone resorption. Despite the absence of bone resorption within the lingual PDL of control mice, distinct resorption sites were seen in the respective regions of the experimental animals. Unlike the controls, many Ruffini endings showing vague and swollen contours, with unusually long and pedunculated micro-projections were observed in the affected lingual PDL of the incisors in the experimental animals with short-term anterior crossbite induction. Club-shaped nerve terminations with few, if any, micro-projections were observed in the lingual PDL of experimental animals with long-term induction, as well as in aged control mouse incisors. Differences in the distribution of Ruffini endings were also observed. These results indicate that changing the direction of the force applied to the PDL results in rapid and prolonged changes in the morphology of Ruffini-like mechanoreceptors.  (+info)

Ectopic eruption of the maxillary canine quantified in three dimensions on cephalometric radiographs between the ages of 5 and 15 years. (5/1158)

The eruption paths of 20 ectopic maxillary canine teeth (10 right, 10 left) were measured in three dimensions on annual lateral and depressed postero-anterior cephalometric radiographs of 15 patients between the ages of 5 and 15 years and compared with the eruption of normal canines. It was found that between the ages of 8 and 12 years ectopic canines on the left side moved more anteriorly than the normally erupting canines and the same was true of the right canines between the ages of 7 and 12 years. While the ectopic canines moved occlusally, their vertical movement was less than normal which accounts for the clinical finding that canines are impacted in the palate at a high level. The average palatally ectopic canine always moves palatally, and never shares in the buccal movement shown by normally erupting canines between the ages of 10 and 12 years. It was interesting to find that the differences between growth of normal and ectopic canines in the lateral plane of space are present as early as 5-6 years.  (+info)

The length and eruption rates of incisor teeth in rats after one or more of them had been unimpeded. (6/1158)

The eruption rate and length of all four incisor teeth in rats were measured under ether anaesthesia by recording the position of marks on their labial surfaces at 2-day intervals, using calibrated graticules in microscope eyepieces. The rats were divided into four groups and either a lower, an upper, both a lower and an upper, or no incisors were unimpeded. This paper describes the changes when the unimpeded incisors returned to the occlusion. Neither the unimpeded nor the impeded incisors simply returned to control values immediately the period of unimpeded eruption ended, but showed transient changes in their lengths and eruption rates. The results confirm that eruption rates are determined by the sum of the lengths of the lower and upper incisors, rather than by their own lengths, with longer teeth erupting more slowly. Specifically, restoring the bevel to the incisors did not slow their eruption below normal impeded rates. The slowing of the eruption of the longer of two adjacent incisors was related to the length differences of the incisors in the same jaw, not to the sum of the differences in both jaws. Contact with the contralateral incisor in the opposite jaw slowed the eruption of an incisor more than contact with the ipsilateral incisor.  (+info)

Expression of chick Barx-1 and its differential regulation by FGF-8 and BMP signaling in the maxillary primordia. (7/1158)

The vertebrate face develops from a series of primordia surrounding the primitive mouth and is thought to be patterned by the differential expression of homeobox-containing genes. Here we describe the isolation of the chick homologue of the homeobox-containing gene, Barx-1, and show its expression in the developing facial primordia, stomach, and appendicular skeleton. In the maxillary primordia, mesenchymal expression of Barx-1 is complementary to that of Msx-1, which correlate with overlying epithelial expression of Fgf-8 and Bmp-4, respectively. We show that epithelial signals are required to maintain Barx-1 expression and that FGF-8 can substitute for the epithelium. By contrast, BMPs reduce Barx-1 expression and can antagonize FGF-8 signaling. This suggests that in vivo, FGF-8/BMP signaling may regulate Barx-1 gene expression. This provides evidence that the differential expression of FGF-8 and BMPs may determine homeobox-containing gene expression and hence patterning of the facial primordia.  (+info)

Jaw reflexes evoked by mechanical stimulation of teeth in humans. (8/1158)

Jaw reflexes evoked by mechanical stimulation of teeth in humans. The reflex response of jaw muscles to mechanical stimulation of an upper incisor tooth was investigated using the surface electromyogram (SEMG) of the masseter muscle and the bite force. With a slowly rising stimulus, the reflex response obtained on the masseter SEMG showed three different patterns of reflex responses; sole excitation, sole inhibition, and inhibition followed by excitation. Simultaneously recorded bite force, however, exhibited mainly one reflex response pattern, a decrease followed by an increase in the net closing force. A rapidly rising stimulus also induced several different patterns of reflex responses in the masseter SEMG. When the simultaneously recorded bite force was analyzed, however, there was only one reflex response pattern, a decrease in the net closing force. Therefore, the reflex change in the masseter muscle is not a good representative of the net reflex response of all jaw muscles to mechanical tooth stimulation. The net response is best expressed by the averaged bite force. The averaged bite force records showed that when the stimulus force was developing rapidly, the periodontal reflex could reduce the bite force and hence protect the teeth and supporting tissues from damaging forces. It also can increase the bite force; this might help keep food between the teeth if the change in force rate is slow, especially when the initial bite force is low.  (+info)

I can sleep a full night with 500g of forward force and 500g of upwards force on my maxilla. When I raise this to 1000g forward and 1000g upwards, my palate becomes sore and I have to remove the headgear. I am working on making the intraoral appliance more comfortable so that I can apply higher forces. The most important design aspect of this appliance is that all of the load is applied on the maxilla, with zero teeth contact. This is important because the teeth can easily be displaced if forces are applied on them. We want to displace the maxilla while leaving the teeth untouched.. The facepulling headgear is only half of the battle. To achieve maxillary protraction in an adult, you need to develop excellent tongue posture and chewing habits. This is done by chewing hard gum regularly and practising tongue posture on a full-time basis.. We know that maxillary displacement is possible in adults, as Dr. Won Moon has been doing non-surgical palatal expansion on adults on a regular basis. Here is ...

Management of bilateral cleft lip and palate cases is a challenging task, and if the premaxilla is shifted to either side, it poses a problem for the surgeon to operate and also for the orthodontist to do the orthodontic alignment. The aim of this study was to reposition the shifted premaxilla for better retraction with presurgical infant orthopedics, thus reducing the tissue tension and further scarring which have detrimental effects on maxillary growth. The innovative technique with pre-directional (PD) appliance is easy to fabricate and use and works in this direction. Acrylic, springs, permasoft liner, elastics, retentive tapes. Previous approach for the shifted premaxilla was more focused on the surgical correction. In adults, surgery with osteotomy is the only option, with its own limitations and disadvantages, in repositioning the shifted premaxilla. Thus, PD appliance aids to correct the shifted premaxilla in presurgical molding stage. The premaxilla was thus shifted 5.5 mm to the left ...

BACKGROUND/AIM: Autotransplantation of teeth to the anterior maxilla may be indicated after trauma or in patients with congenitally missing teeth. The aim of this systematic review was to report the current evidence concerning survival and success rate, aesthetic outcome, and patient-reported outcome of autotransplanted teeth to the anterior maxilla.. MATERIALS AND METHODS: A MEDLINE search followed by an additional hand search was performed to identify relevant literature. All levels of evidence except case reports were considered. Any publication reporting on 10 or more autotransplanted teeth to the anterior maxilla, and written in English were eligible for this systematic review.. RESULTS: The systematic search identified 95 abstracts. Thirty-seven full-text articles were evaluated of which 17 could finally be included. Data on survival and success rate of the transplants could be extracted from 11 studies. Survival rates ranged between 93% and 100% (weighted mean: 96.7%, median: 100%) after ...
The protopod of the maxilla 2 of copepods is composed of a proximal syncoxa with a praecoxal endite proximally and a coxal endite distally. The basis bears two endites, and the ramus is an endopod bearing up to five segments. This interpretation is based on protopodal patterning from the point where the limb articulates with the body, and the assumption that this patterning should result in a derivable enditic configuration on the protopod of the serially homologous limbs maxilla 1 anteriorly and maxilliped posteriorly. Processes that affect the morphological diversity of maxilla 2 among copepods include: truncation of protopodal segmentation, suppression of enditic extension, truncation of endopodal segmentation, and segment elongation. Hypotheses about transformations of the basis suggest the following synapomorphies: neither endite of the basis is attenuate on maxilla 2 of Poecilostomatoida; the basis of maxilla 2 of Siphonostomatoida is elongate ventrally. Le protopodite de la seconde maxille des
The second maxillary bone The second bone (D in fig. 1) [os lacrimale] of the maxilla, far smaller than all the others and thin like a scale, is located in the inner angle [angulus oculi medialis] of the eye socket where there is a foramen [fossa sacci lacrimalis] (C in fig. 1) in front of which is a caruncle [caruncula lacrimalis] that occupies the inner angle of the eye. This is said to have been created to prevent any phlegm purged from the brain into the eye sockets from flowing down onto the cheeks, but instead to fall completely through this foramen [ductus nasolacrimalis] into the space of the nostrils. This ossicle [os lacrimale] is terminated in its upper portion [crista lacrimalis] by a short interval of suture [sutura frontolacrimalis et sutura frontomaxillaris] (from V to X in fig. 1) that distinguishes the frontal bone from the upper maxilla; it is therefore by this suture that this ossicle is joined to the frontal bone. From this suture, a second one [sutura ethmoidolacrimalis] (in ...

Chapter 2. Variations in Transition of Mandibular Incisors*. 2.1 Introduction The mandible precedes the maxilla in the transition of the incisors. The first deciduous tooth to be lost - the mandibular central incisor - is exfoliated about 1 year earlier than the corresponding maxillary incisor.. The tooth-containing parts of the mandible differ markedly from those in the maxilla in size, shape, and structure. Consequently, the transition of the mandibular incisors differs from that of the maxillary incisors. In the mandible less space is available for the crowns of the not-yet-erupting permanent teeth and the roots of the deciduous and permanent ones than in the maxilla. Further, the mandible does not have an interstitial growth site in the form of a midsagittal suture that can contribute to an increased transverse jaw dimension in the median plane. The aforementioned differences partly explain why the transition of incisors in the mandible varies less than that in the maxilla.. The combination ...
Rennan Carvalho Paim, Herbert De Abreu Cavalcanti, Adenir João Biesek, Gustavo Silva Pelissaro, Rodrigo Dalla Lana Mattiello Reconstruction of atrophic maxilla is a difficult procedure performed by means of maxillofacial surgery, there being a wide range of techniques and material available for its execution. Autogenous bone is the gold standard for grafting; however, its use has disadvantages that create a demand for new types of material. Thus, this article reports the case of atrophic maxilla reconstruction with of BMP-rh2 associated with Bio-OssTM. An edentulous female patient with atrophic maxilla underwent reconstructive surgery carried out with BMP-rh2/ACS and Bio-OssTM, in which bilateral sinus lift and on-lay graft were performed in the anterior maxilla. The grafted area was protected with a titanium mesh, previously shaped with the aid of a custom template. After six months, clinical and imaging examination evinced bone formation; and after 12 months, this new bone was used for ...
To this study a group of 79 patients (36% male and 64% female), average age of 59 years old (ranging from 36 to 85 years old), showing atrophic maxilla, with less than 3 mm on sinus and no more than 5 mm on pre maxilla. On this group, patients presented 7 lacks of bone on maxilla 2 due to ablative surgery, 1 for previously bone graft failures, 4 due to failure of fibrous integrated implants. Associated with 185 zygomaticus fixtures, 225 conventional conic implants were installed on the anterior maxilla (ranging from 2 to 6 implants) and 11 implants were fixed on the pterigoideo bone in order to achieve better anchorage and force distributions among the implants for the prosthesis. ...

Here, we enumerate derived character states that bear on the Placement of Sarahsaurus among sauropodomorphs. The external narial margin is formed by the premaxilla and nasal, with a small contribution from the maxilla. Behind the premaxillary teeth, a posterolateral process overlaps the maxilla along the posteroventral corner of the naris. The palatal shelves of the premaxillae are narrow and enclose an incisive foramen between them. A large subnarial foramen penetrates the descending segment of the suture between the premaxilla and maxilla above the tooth row, and a small neurovascular foramen is situated above the alveolar margin behind the first tooth on the right premaxilla.. The maxilla has a subnarial ramus that is longer than deep. A shelf-like area lateral to the external naris extends onto the anterior end of the maxilla. There are at least seven distinct neurovascular foramina on the lateral surface of the maxilla, the last of which opens posteriorly. The medial shelves of the maxillae ...
Twelve adults with maxillary width discrepancy of greater than 5 mm were trated by surgicaly assisted rapid maxillary expansion. The procedure consisted of bilateral zygomatic buttress and midpalatal osteotomies combined with the use of a tooth-borne orthopedic device postoperatively. Mean palatal expansion of 7.5 mm (range of 6 to 13 mm), measured in the first molar region was achieved within 3 weeks in all patients. Expansion remained stable during the 12-month study period, with a mean relapse for the entire group of 0.88 +- 0.48 mm. Morbidity was limited to mild postoperative discomfort. The results of this preliminary study indicated that surgically assisted rapid maxillary expansion is a safe, simple, and relaible procedure for achieving a permanent increase in skeletal maxillary width in adults. Further study is necessary to document the three-dimension movements of the maxillary segments and long-term stability of the skeletal and dental changes. ...
The accuracy of positioning the osteotomized maxilla during orthognathic surgery was assessed in 26 patients, comparing the use of an external reference point placed on the forehead skin (SERP), and an external reference point consisting of a bone screw placed at the forehead bone (BERP). In all cases, the unoperated mandible was used to provide an anteroposterior and transverse maxillary position, through use of an intermediate splint. In 14 cases, the distance between the SERP and the maxillary central incisor was measured, to determine the maxillary vertical dimensions. In 12 cases, measurements between the BERP the and maxillary central incisor were made.,BR,All preoperative lateral cephalometric radiographs were traced by one investigator, and these tracings were superimposed on postoperative lateral chephalograms (3 to 6 days after surgery), respectively. The actual changes in the vertical and horizontal position of U1 were measured perpendicular and parallel to the Frankfort horizontal ...
