Evaluation of Edentulous Maxillary and Mandibular Full Arch Implant Supported Rehabilitation Using the All-on-Four Treatment Concept: An 8-Year Follow-Up Retrospective Study.

The "all-on-four" treatment modality is a treatment in which four implants are surgically placed in the completely edentulous jaw in order to restore immediately loaded implant supported fixed restoration. The aim of the present study was to compare clinical, radiological and prosthetic outcomes of immediately loaded maxillary and mandibular four implant supported cross-arch fixed denture prosthesis. A total of 112 edentulous patients who were rehabilitated for their complete maxillary and mandibular edentulism using All-on-four concept between January 2010 to August 2012 in four private dental clinics were included in this study for retrieve their data for marginal bone loss, implant survival rate, and prosthetic complication for a period of 8 years of follow-up.

Vertical ridge augmentation using deproteinized bovine bone material without covering with a membrane: a tunnel pouch technique- 4-year follow-up- A pilot clinical study.

Purpose Of The Study-: The present pilot clinical trial was planned to evaluate the effect of particulate deproteinized bovine bone graft mixed with blood could be used as a vertical ridge augmentation material without covering with any form of collagen membrane in a tunnel pouch technique, resulting in sufficient bone formation to allow placement of dental implants, with maintenance of the newly formed bone after final restoration.

Material And Methods—: Eight patients (three males and five females) were selected for this procedure and treated between February 2016 and December 2017. All these patients had a deficient vertical height of the posterior mandibular alveolar bone above the inferior alveolar canal.

Troubleshooting Ocular Prosthesis: A Case Series.

This case series reports on clinical challenges faced during the rehabilitation of custom ocular prosthesis. Each of these cases relate the challenges of making ocular impressions for an improved retention and support of ocular prosthesis and presents the significance of scleral contouring in overcoming cosmetic defects of the eye. In addition, evaluation of scleral wax pattern, methods of iris location and scleral characterization methods in ocular rehabilitation are further discussed.
