BACKGROUND
We evaluated cone beam computed tomography images to compare the complexity of dental implant surgery after alveolar ridge preservation in damaged versus intact sockets resulting from severe periodontitis-related tooth extraction.
METHODS
In a retrospective analysis of 165 alveolar ridge preservation sites among 116 patients, we categorized 72 sockets as damaged and 93 as intact. Using cone beam computed tomography, we measured bone width at three vertical levels and compared bone regeneration needs for subsequent dental implant surgery between socket types.
RESULTS
Despite no difference in bone width between damaged and intact sockets, implant placement revealed differing regenerative needs. Mandibular teeth and non-drinkers required less regeneration. Damaged sockets exhibited 3.02 times higher regeneration requirements compared to intact ones.
CONCLUSIONS
The complexity of implant surgery following alveolar ridge preservation is influenced by alcohol consumption, tooth position, and periodontitis-related tooth extraction.

背景
我们评估了锥形束计算机断层扫描图像，以比较在因重度牙周炎相关拔牙导致的受损牙槽窝与完整牙槽窝中进行牙槽嵴保存后牙种植手术的复杂性。
方法
在对116例患者的165个牙槽嵴保存部位进行的回顾性分析中，我们将72个牙槽窝分类为受损牙槽窝，93个为完整牙槽窝。使用锥形束计算机断层扫描，我们在三个垂直层面测量了骨宽度，并比较了不同类型牙槽窝后续牙种植手术的骨再生需求。
结果
尽管受损牙槽窝和完整牙槽窝之间的骨宽度没有差异，但种植体植入显示出不同的再生需求。下颌牙和不饮酒者需要的再生较少。与完整牙槽窝相比，受损牙槽窝的再生需求高出3.02倍。
结论
牙槽嵴保存后种植手术的复杂性受饮酒、牙位和牙周炎相关拔牙的影响。
