(1/49) The status of oral hygiene in cleft lip, palate patients after surgical correction.
The cleft lip and palate patients usually present a number of problems viz. altered oral anatomy leading to changes in oral physiology diminishing the self-cleansing ability of individual. The handicapped children are unable to maintain their oral hygiene properly. The present study was formulated with the aim that does normalization of oral anatomy have its effect on improvement of oral hygiene? An assessment of oral hygiene index-simplified was performed between preoperative and postoperative values in the same patient at KGMU and KGDU. A total of 50 cases were recorded in two groups of 25 each: (i) 6 years. The observations are statistically analyzed by paired 't' test to get the significance of results. RESULTS: The data analyzed showed the significant decrease in oral hygiene indices observed in both groups. A relative significance in oral hygiene status following surgery was observed. Both groups expressed greater significance when compared pre and postoperatively which is indicative of considerable improvement of oral hygiene after surgical correction. The study concludes that oral hygiene improves more in older cleft lip-palate cases following reconstruction of palatal vault, premaxilla and anterior lip seal by secondary bone grafting method when compared with oral hygiene indices results in primary periosteoplasty cases. The surgical correction of cleft lip palate enhances self-cleaning ability and better compliance to maintain oral hygiene in children as the age advances. (+info)

(3/49) Influence of mandibular fixation method on stability of the maxillary occlusal plane after occlusal plane alteration.
In this study, we investigated how method of mandibular fixation influenced longterm postoperative stability of the maxilla in Class III cases. In particular, we investigated change in the maxillary occlusal plane after Occlusal Plane Alteration. Therefore, we focused on change in the palatal plane to evaluate stability of the maxillary occlusal plane, as the position of the palatal plane affects the maxillary occlusal plane. This study included 16 patients diagnosed with mandibular protrusion. Alteration of the occlusal plane was achieved by clockwise rotation of the maxilla by Le Fort I osteotomy and mandibular setback was performed by bilateral sagittal split ramus osteotomy. We analyzed and examined lateral cephalometric radiographs taken at 1 month, 3 months, 6 months, and 1 year after surgery. Stability achieved by two methods of mandibular fixation was compared. In one group of patients (group S) titanium screws were used, and in the other group (group P) titanium-locking mini-plates were used. No significant displacement was recognized in group S, whereas an approximately 0.7mm upward vertical displacement was recognized in the anterior nasal spine in group P. As a result, not only the angle of the palatal plane and S-N plane, but also occlusal plane angle in group P showed a greater decrease than that in group S. The results suggest that fixing the mandible with screws yielded greater stability of the maxilla and maxillary occlusal plane than fixing the mandible with titanium plates. (+info)
(4/49) The process of orthognathic care in an NHS region.
(5/49) Six-year follow-up in skeletal Class III patient aged over 40 receiving orthognathic surgery and autotransplantation: a case report.
This paper describes the post-operative course of care in a patient requiring orthognathic surgery for skeletal mandibular protrusion in whom autotransplantation of a third molar was performed. A lower third molar that had to be removed for sagittal split ramus osteotomy (SSRO) was transplanted to replace the missing right second molar during pre-surgical orthodontic treatment, contributing to post-treatment occlusal stability. A 44-year-old woman presented with mandibular protrusion. The upper left second molar was congenitally missing and the lower right second molar had been extracted. She was diagnosed as having skeletal mandibular protrusion with excess vertical growth of the mandible and anterior open bite. Correction of the skeletal problem required orthognathic surgery by SSRO and Le Fort I osteotomy without orthodontic tooth extraction. At month 5 during 18 months of pre-surgical orthodontic treatment, the lower left third molar was transplanted to the lower right second molar site. Active treatment was completed after 7 months of post-surgical orthodontic treatment. The patient wore upper and lower Begg-type removable retainers for approximately 2 years. She returned for a recall checkup at 6 years post-treatment. Although radiographic examination revealed root resorption and ankylosis of the autotransplanted tooth at 8 years after transplantation, occlusion has remained stable with no clinically significant complications. The autotransplanted tooth helped stabilize her occlusion and acted as a kind of temporary tooth prior to the final decision on treatment to be given such a dental implant. (+info)

Gastro-esophageal reflux is a gastrointestinal disorder that might cause irreversible damages to the hard tissues of the teeth. The aim of this article is to report two cases of patients with severe dental demineralization associated with gastro-esophageal reflux during orthodontic and combined orthodontic-orthognathic surgery treatment. Diagnosis and prevention aspects are highlighted and discussed. (+info)
(7/49) Ostectomy versus osteotomy with repositioning of the vestibular cortical in periapical surgery of mandibular molars: a preliminary study.
INTRODUCTION: Accessing the tooth roots in periapical surgery (PS) requires the elimination of periapical bone. OBJECTIVE: To compare the postoperative morbidity and prognosis following PS on mandibular molars by ostectomy, or by osteotomy with repositioning of the vestibular cortical. MATERIAL AND METHODS: A retrospective clinical study of mandibular molars subjected to PS with ultrasound. Two groups were considered according to the surgical procedure used to access the roots: Group 1 (G1) with ostectomy and Group 2 (G2) with osteotomy and repositioning of the vestibular cortical. Only patients who had properly followed the post-operative instructions, adequately completed the post-operative questionnaires, and with a minimum of 12 months follow-up were included in the study. Post-operative morbidity was evaluated, and a clinical and radiographic follow-up was carried out using the criteria established by von Arx and Kurt in 1999. The SPSS program version 15 for Windows was used, considering values of p < or =0.05 as statistically significant. RESULTS: Seventy-five patients, including 18 men and 57 women, with 87 mandibular molars and 107 periapical lesions were subjected to PS. The mean age of the patients was 38.5 years old (range 15-74 years old). The patients were monitored for an average of 27.2 months (range 12-120 months). Sixty-six patients (78 teeth) were treated in G1, and 9 patients (9 teeth) in G2. There was no relationship between the size of the ostectomy and pain, swelling or prognosis (p>0.05). Patients who underwent ostectomy presented more swelling than those subjected to osteotomy (p<0.05). There was no relationship between prognosis and the variables studied (p>0.05). CONCLUSIONS: There was no statistically significant relationship between the surgical procedure used and post-operative pain or prognosis. Patients who underwent an ostectomy presented more swelling than those who were treated with an osteotomy and repositioning of the vestibular cortical. (+info)
