Dental Implants

Brief summary

The aim of the present study was to evaluate the accuracy of a prefabricated digitally planned provisional restoration on a single- implant placed with a fully guided surgical protocol.

Detailed description

Fifteen dental implants were placed in partially edentulous patients with single bounded lower posterior edentulous area selected from those admitted to the Prosthodontics Department, Faculty of Dentistry, Alexandria University. A full digital implant-prosthetic protocol was followed and a quantitative evaluation of the accuracy of the protocol was performed using computer software and superimposition of the planned and post-operative images was done.

Interventions

OTHERVirtual Implant Planning

According to the virtual implant plan, a CAD/CAM tooth supported surgical guide will be fabricated to place the dental implant with a fully guided surgical protocol.The surgical guide will be manufactured from a photopolymer resin using a 3D printing machine. A hex- shaped metal sleeve will be inserted in the surgical guide with the flat surface located buccally so that it will help in orientation of the implant hex during the implant placement.

Design outcomes

Primary

Measure	Time frame	Description
3D- Deviation of the implant	3 months	The 3D deviation will be calculated by a software taking into consideration the deviation on each direction set as follows: x= buccolingual error, y= mesiodistal error, and z= apicocoronal error, using Pythagorean Theorem: 3D deviation= square root of (x squared + y squared + z squared)
