Prosthetic Management Of Interruptive Mandibular Defects, Saloua Hamzaoui, Mohamed Azhari, Hasnaa Rokhssi, Majid Sakout, Oussama Bentahar

International Arab Journal of Dentistry

Mandibular substance loss is one of the most frequent acquired defects of the maxillofacial mass. Several etiologies have been described, the most frequent of which are tumours and traumas. The most commonly used prosthetic classification takes into consideration the bone continuity of the mandible, thus there are marginal defect mandibular substance preserving bone continuity and segmental defect with basal bone discontinuity. These bone defects lead to numerous functional complications (loss the dental occlusion, decreased chewing efficiency, lack of stalling during swallowing, phonatory disorder related to the change in the buccal resonance cavity) and aesthetic complications (facial asymmetry due to lateral …

An Overview Of Maxillofacial Rehabilitation For The General Dentist, Vladimir Frias Dds, Ms

The New York State Dental Journal

The rehabilitation of the maxillofacial patient is mostly carried out in a multi-specialty treatment environment such as a comprehensive cancer center, where multiple specialists are available to treat the numerous concerns and complications that may occur. Many of these patients are seen by the maxillofacial prosthodontist at the same time as the other members of the team and maxillofacial rehabilitation can be treatment planned and performed expediently. Some patients, however, are treated without rehabilitation in mind and go years without appropriate referrals. A knowledge of the multiple types of prostheses available will allow the general practitioner to decide if a …

10-Minute Ebd: Are Neoplasms A Risk Factor For Peri-Implantitis?, Farah Safieddine Bs, Naama Sleiman Ms, Phd, Melanie E. Mayberry Dds, Ms-Hcm

The Journal of the Michigan Dental Association

This 10-Minute EBD column explores the potential association between neoplasms and the risk of peri-implantitis in patients with dental implants. A case study involving a patient with a history of an ossifying fibroma raises questions about the impact of neoplasms on implant success. The literature search, conducted on PubMed, reveals relevant insights. The evidence suggests that ossifying fibromas, particularly with augmentation, may pose a risk for peri-implantitis. However, the direct causative relationship between neoplasms and peri-implant pathology remains unclear. Other risk factors such as periodontitis, foreign bodies, and augmentation procedures are also discussed in the context of implant complications.
