DLP Versus SLM Stackable Surgical Guide

Purpose; The purpose of this research is to make a comparative estimation for the positional accuracy of dental implants inserted by selective laser melting and digital light processed computerized stackable surgical guides for patients with maxillary terminal dentitions.Materials and methods; Twenty-four dental implants will be installed in partially edentulous patients who will be applied for treatment of tooth loss and required fixed prosthodontic rehabilitation. Virtually designed prosthetically driven fixation base with its stackable surgical osteotomy guide will be used for bone reduction after tooth extraction and osteotomy preparation respectively. The inserted implants will be divided equally into two groups according to stackable surgical osteotomy guide to either selective laser melting (SLM) CO-Cr metal or digital light processing (DLP) surgical-guides. The final actual implant position will be compared to the preoperative planned position and the deviations will be calculated for coronal deviation, apical deviation in mm, and two angular deviation measurements in degrees.

Inclusion Criteria:well healthy patientspatients with maxillary terminal dentitionExclusion Criteria:Patients with, systemic disease that might complicate post-operative healing or contribute to bone resorptionpatients with parafunctional habits, poor oral hygiene, limited mouth opening, severe alveolar bone deficiencies,patients with uncontrolled diabetes, current irradiation to the head or neck, psychological disorders, or alcohol, tobacco, or drug abuse
