研究概览
简要总结
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.
详细描述
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.

结局指标
主要结局
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
时间窗: 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.
