简要总结
The aim of this study is to evaluate the volume of madibular bone after placement of a xenograft in a fresh extraction socket in human. 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 35 patients.
详细描述
Primary objective :
Estimate the percentage of loss of bone volume and the percentage thickness loss of the buccal and palatal cortical for patients who underwent bone volume preservation technology and conservation of the vestibular cortical by guided bone regeneration using a material slow absorption in the molar areas and premolar.
Secondary objectives:
Compare the percentage of loss of bone volume and the percentage loss of thickness of the buccal and palatal cortical patients who underwent a preservation technique, the upgrading data of mandibular posterior region without fillers described in the literature.

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
- Clinical measures(Day of surgery)
- Cone beam pre implant examination(5 or 6 months)
