About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Patients missing lower first molar unilaterally or bilaterally.
Presence of full or nearly full complement of opposing natural teeth.

Exclusion criteria

If teeth adjacent to the planned implant site showed infections, endodontic or periodontal problems.
Patients with a debilitating systemic disease, bone diseases, radiotherapy or chemotherapy.

Treatment and study plan

Virtual Implant Planning

Other

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.

Primary outcomes

3D- Deviation of the implant

Time frame: 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)
