Accuracy Evaluation of the Computer-Designed Selective Laser Sintering Surgical Guide for Flapless Immediate Loading Dental Implants Surgery in Edentulous Jaws.

This study was designed to evaluate the accuracy of a novel computer-designed and selectively laser sintered surgical guide for flapless dental implant placement in the edentulous jaw. Fifty dental implants were placed in 11 patients with at least 1 totally edentulous jaw. Initially, cone-beam computed tomography (CBCT) was performed in each patient to define the virtual position of the dental implants based on the assessment of bone availability and the proposed dental prosthesis.

A selective laser sintering prototype guide used to fabricate immediate interim fixed complete arch prostheses in flapless dental implant surgery: Technique description and clinical results.

Statement Of Problem: Extensive occlusal adjustments and misfit of the prosthesis to prosthetic components are frequent problems related to fixed interim prosthesis fabrication with immediate dental implant loading.

Purpose: The purpose of this clinical trial was to evaluate a prosthetic guide made with a rapid prototype model based on virtual surgical planning. This prosthetic guide was used to fabricate fixed interim prostheses that would allow immediate implant loading after computer-guided implant installation.

Monoscopic photogrammetry to obtain 3D models by a mobile device: a method for making facial prostheses.

Purpose: The aim of this study is to present the development of a new technique to obtain 3D models using photogrammetry by a mobile device and free software, as a method for making digital facial impressions of patients with maxillofacial defects for the final purpose of 3D printing of facial prostheses.

Methods: With the use of a mobile device, free software and a photo capture protocol, 2D captures of the anatomy of a patient with a facial defect were transformed into a 3D model. The resultant digital models were evaluated for visual and technical integrity.

Assessment of orbital volume in frontofacial advancements.

Objectives: The objective of this study was to evaluate the variation of the orbital volume and the correlation with the magnitude of craniofacial advances as well as demonstrate its effectiveness through comparisons with normal levels of orbital volumes.

Introduction: Syndromic craniofacial synostosis is characterized by cranial morphological alterations and hypoplasia of the midface that may result in obstructive sleep apnea and exorbitism; these effects are indications of surgical treatment. The gradual advancement of tissues is the surgical treatment to correct accentuated exorbitisms and jaw retrusions.

Accuracy and complications of computer-designed selective laser sintering surgical guides for flapless dental implant placement and immediate definitive prosthesis installation.

Background: Computer-aided dental implant placement seems to be useful for placing implants by using a flapless approach. However, evidence supporting such applications is scarce. The aim of this study is to evaluate the accuracy of and complications that arise from the use of selective laser sintering surgical guides for flapless dental implant placement and immediate definitive prosthesis installation.
