简要总结
The aim of this study is to evaluate the bone loss after extraction. The surgery protocol is flapless, and the teeth are mandibular premolars or molars leaving sockets with 4 walls intact or at least 3 walls intact and the buccal wall at 80% . This study will include 40 patients
详细描述
Primary objective :
Estimate the percentage of bone volume loss o and the percentage thickness loss of the buccal and palatal cortical for patients who underwent natural healing in the mandibular molar and premolar areas.
Methods :
Before tooth extraction of a premolar or molar in mandibular area by flapless technique, a CBCT preoperative is performed to verify the integrity of cortical and measure the height and width of the residual cavity. Caliper measurements will also be performed during surgery in order to integrate also the thickness of the bone tables and gingival thickness.
After natural healing , the pre-implant scan performed at six months postoperatively will measure the height and width of the grafted cell, to compare measurements and evaluate the dynamics of alveolar resorption.

结局指标
主要结局
Cone beam diagnostic examination
时间窗: Day diagnostic (Day 0)
Cone beam diagnostic examination: Millimeter measurements will be taken at Day 0. This examination is an X-ray technique that uses a cone-shaped radiation beam. The measurements will be made on radiographic examinations Mucous measures * Vestibular cortical Distance, lingual cortical measured in the middle of the cell * Depth of the slot lingual cortical side * Depth of the cell vestibular cortical side Bone measures * Thickness of the lingual cortical measured caliper 2 millimeters under the rim * Vestibular cortical thickness measured with calipers 2 millimeters under the rim * Depth of the slot lingual cortical side * Depth of the cell vestibular cortical side
次要结局
- Cone beam pre implant examination(5 or 6 months)
- Clinical measures(Day of surgery)
