Dental implant placement by predoctoral dental students: a pilot program.
(34/45)
Dental implant education is increasingly becoming part of predoctoral dental curricula. New York University College of Dentistry has developed a pilot dental implant program that trains students in implant restorations for single-tooth restorations and mandibular overdentures. Fourth-year students have the option of applying for an implant honors program, which can include surgically placing posterior implants. Eight students were selected for the implant honors program for the 2010-11 academic year. Seven of the eight students fulfilled the didactic and simulation requirements, performing forty-seven surgeries and placing fifty-two implants. Surgical protocol events were recorded: three implants did not achieve 35 Ncm torque at placement, and ten implants required a change in direction following the initial 8 mm pilot drill. All direction changes were successfully performed and resulted in implant placements. This pilot program suggests that predoctoral dental students can be trained to successfully place posterior implants, which are becoming the standard of care. (+info)

Imaging technique for the complete edentulous patient treated conventionally or with mini implant overdenture.

RATIONALE: The imaging methods are more and more used in the clinical process of modern dentistry. Once the implant based treatment alternatives are nowadays seen as being the standard of care in edentulous patients, these techniques must be integrated in the complete denture treatment. AIM: The study presents some evaluation techniques for the edentulous patient treated by conventional dentures or mini dental implants (mini SKY Bredent) overdentures, using the profile teleradiography. These offer data useful for an optimal positioning of the artificial teeth and the mini dental implants, favoring to obtain an esthetic and functional treatment outcome. We proposed also a method to conceive a simple surgical guide that allows the prosthetically driven implants placement. MATERIAL AND METHOD: Clinical case reports were made, highlighting the importance of cephalometric evaluation on lateral teleradiographs in complete edentulous patients. A clinical case that gradually reports the surgical guide preparation (Bredent silicon radio opaque), in order to place the mini dental implants in the best prosthetic and anatomic conditions, was presented. CONCLUSIONS: The profile teleradiograph is a useful tool for the practitioner. It allows establishing the optimal site for implant placement, in a good relation with the overdenture. The conventional denture can be easily and relatively costless transformed in a surgical guide used during implant placement. (+info)

Rehabilitation of a patient with an elusive medical history and loss of occlusal vertical dimension.
(40/45)
In this clinical report, we describe the medical history, diagnosis and prosthodontic treatment of a 61-year-old man with a previous history of oral cancer. Loss of a full upper denture and severe erosion of his teeth prompted the patient to seek treatment at the dental clinic at the British Columbia Cancer Agency. Although he stated that he was being treated for a sleeping disorder, hospital records revealed multiple recent admissions for alcoholism and depression. The patient's limited finances prevented complex restoration of worn lower dentition; thus, definitive treatment consisted of extraction of teeth with a poor prognosis, removal of a glandular odontogenic cyst and fabrication of a full maxillary prosthesis and a removable mandibular cast-metal overlay.
