Pterygoid Implant-Retained Bridge Following Multiple Failed Alveolar Implants In Posterior Maxilla, Kouder Dakhallah Dds, Anish Gupta Dds, Joey Wilmot, Brian Giammalva Dds

The Journal of the Michigan Dental Association

The replacement of multiple teeth with dental implants in the posterior maxilla is challenging due to factors including low density bone and sinus morphology. When considering restoration of this region, prosthetic design will dictate implant placement. Additionally, planning must consider spacing between adjacent implants, spacing between implants and adjacent teeth, and irregular alveolar ridge morphology. These key measurements translate to the final prosthesis design and will affect cleanability and future oral hygiene maintenance. These characteristics subsequently affect overall longevity of the implants and prosthesis.

In the following case, multiple closely-placed implants presenting with poor cleanability consequently failed, requiring removal and …

Toward Electrical Impedance Sensing Surgical Drill For Tissue Boundary Detection, Harshavardhan Devaraj

Dartmouth College Ph.D Dissertations

Dental implantation is an increasingly common procedure used to treat missing teeth. However, surgical drilling to place the implant poses a high risk of injury to critical anatomy, such as inferior alveolar nerve injury or maxillary sinus perforation. A real-time surgical feedback system sensing proximity of these critical anatomy could reduce injury risks. This dissertation investigates the development of such a system that incorporates an electrical impedance sensor into the tip of a surgical drill.

A simulation framework based on finite element method (FEM) was developed to optimize the sensor as it approached a high impedance boundary. The accuracy of …

Peri-Implantitis Incidence And Effect Of Supportive Periodontal Therapy On Outcomes: Retrospective Cohort Study, Michael Ha

Theses and Dissertations

Purpose: Management of peri-implantitis is becoming an increasing component of dental practice. Dental implants can develop peri-implantitis lesions which occur in a non‐linear and accelerating pattern compared to a gradual periodontitis lesion. It is crucial to diagnose and treat this disease early, or ideally prevent it. Contemporary implants have a rough surface texture which is difficult to properly decontaminate as a crucial component for treatment prognosis. Evidence on the long-term effects of Periodontal implant maintenance therapy (PIMT) on implants is limited. This study aims to investigate the effect of periodontal maintenance on peri-implant tissue health.

Methods: A retrospective chart review …
