Current trends to measure implant stability

Implant stability plays a critical role for successful osseointegration. Successful osseointegration is a prerequisite for functional dental implants. Continuous monitoring in an objective and qualitative manner is important to determine the status of implant stability. Implant stability is measured at two different stages: Primary and secondary. Primary stability comes from mechanical engagement with cortical bone. Secondary stability is developed from regeneration and remodeling of the bone and tissue around the implant after insertion and affected by the primary stability, bone formation and remodelling. The time of functional loading is dependent upon the implant stability. Historically the gold standard method to evaluate stability were microscopic or histologic analysis, radiographs, however due to invasiveness of these methods and related ethical issues various other methods have been proposed like cutting torque resistance, reverse torque analysis, model analysis etc. It is, therefore, of an utmost importance to be able to access implant stability at various time points and to project a long term prognosis for successful therapy. Therefore this review focuses on the currently available methods for evaluation of implant stability

Fabrication of a closed hollow bulb obturator for the rehabilitation of an acquired partial maxillectomy defect due to mucormycosis

Patient affected from post-COVID mucormycosis often require local debridement or surgical resection resulting in maxillectomy. This is frequently quite extensive or bilateral and spares very little of the hard and soft tissues in the oral cavity. Both surgery and prosthetic rehabilitation are needed to rehabilitate such extensive defects. Once the patient has grown accustomed to the temporary prosthesis and effective healing has taken place, a definitive prosthesis is inserted for the patient. Definitive obturators require careful thought during design to ensure longevity and superior retention and stability. This article documents the prosthetic rehabilitation of a partial maxillectomy defect due to mucormycosis which resulted after COVID

Application of robotic technology in prosthodontics

There is a huge technical leap in dentistry from the traditional manual methods toward digital technology. The invention of robots has minimized manual efforts in hazardous working environments thus leading to better accuracy and precision of the work. Robotic application in prosthetic dentistry is utilized for removable prosthodontics and implant surgeries. The time required to complete each procedure is expected to be considerably reduced with the use of robots
