Overview
Brief Summary
The aim is to study bone and soft tissue response to zirconia immediate implants.Volumetric changes will be measured before tooth extraction and after final crow placement.
Detailed Description
Bone remodeling around immediate implants is a reality in clinical and literature arena. much is known about titanium implants but little in zirconia implants In patients that require a tooth extraction anywhere in the oral cavity except 3rd molars are candidates fo the study. Once clinical conditions are establish and medical clearance is ok, the decision for an immediate implant is taken. Patient will undergo for an intraoral Scanner (IOS, Trios 3Shape) to get an STL file of the previous situation. On the day of surgery an atraumatically tooth extraction is performed (without rasing a flap) and a Zirconia implant is inserted on the alveolar socket. The jumping gap (distance from crystal bone to implant body will be filled with a zenograft type of biomaterial) no sutures or membrane will be used. A provisional crown or an individualized healing abutment will be placed. After 3 month healing an IOS will be made for crown fabrication and a second STL file generated. After 15 days final crown will be placed, and 3 month after a 3rd IOS made to get the 3rd and final STL file. An STL software will then make the correlation between the volume behavior in those 3 stages. The control group, patients go for tooth extraction but no immediate implant and undergo with a classic protocol for implant placement. In this case the STL files are taken pre-operatory, before implant placement 3 month after tooth extraction, 2 month after implant placement (at final impression level), and 3 month after crown placement.

Outcomes
Primary Outcomes
Ridge dimensions (Bone and soft tissue from buccal to palatal) Changes from final impression (Day 2 ) to 2 month after osseointegration (Day 3), in Zirconia Immediate Implants
Time Frame: 1Year
Physiologic resorption rate from Day 2 - Day of final Impression to Day 3- 3 month after final crown insertion measured by STL superimposition. Acquisition of STL File with an IOS in both time frames, and in an STL reader software (Geomagic Control X) we merge them with the corresponding common landmarks for a best fit alignment. Measure include, Total bone and soft tissue volume loss (in cubic centimeters). Bone collapse measured in mm from the most buccal point to most palatal point of the ridge.
