Supporting data for "Alveolar healing patterns following molar loss: Assessment, prediction and clinical implications in implant rehabilitation"

Placement of dental implants with and without various forms of tissue reconstruction in the molar region is becoming a more common treatment modality for the replacement of missing teeth as a consequence of dental diseases or trauma. However, to date, there is little evidence reporting on the healing patterns and the feasibility of implant placement at molar sites with tooth loss due to terminal periodontitis versus other reasons following unassisted healing. There is also a lack of reporting of local, systemic and surgical variables associated with healing outcomes. This information is crucial for the establishment of the best clinical pathway to manage the extraction of molars. Data will help clinicians predict healing outcomes and form a basis for decisions on the choice of implant, need for intervention and designing interventions to modulate the healing process, aiming to simplify subsequent surgeries for replacement with dental implant. Hence there is a need for a cohort study to demonstrate the potential difference in healing following different reasons for extraction and to assess the ability to place implants in these different healed sites. This is a 3 part study that will systematically investigate the hard and soft tissue dimensional remodelling following molar loss utilizing CBCT and digital scanning technology. The reliability of these technologies in assessing hard and soft tissue will also be investigated. Study results will help clinicians better understand and predict alveolar hard and soft tissue healing outcomes after tooth loss at molar sites that will impact clinical decisions in tooth rehabilitation.This project consists of 3 main parts:1. Systematic review of alveolar healing patterns after loss of molar;2. Retrospective study on the feasibility of implant placement at molar sites with tooth loss due to severe periodontitis;3. Prospective study on the alveolar healing patterns after extraction of the first molar.

牙髓植入术在有无各种形式组织重建的情况下，已成为替换因牙病或创伤而缺失牙齿的更为常见的治疗方式。然而，迄今为止，关于因晚期牙周炎或其他原因导致的牙齿丧失后，在磨牙区进行植入术的愈合模式和可行性的报道证据尚显不足。同时，关于与愈合结果相关的局部、全身和手术变量的报道也极为匮乏。此类信息对于确立最佳临床路径，以管理磨牙的拔除至关重要。这些数据有助于临床医生预测愈合结果，并为选择植入物、干预的必要性以及设计调节愈合过程的干预措施提供依据，旨在简化后续的牙齿植入手术。因此，有必要进行一项队列研究，以证明因不同原因拔牙后愈合的潜在差异，并评估在这些不同愈合部位植入牙齿的能力。这是一项分三部分的研究，将系统地利用锥束CT和数字扫描技术，研究磨牙丧失后的硬组织和软组织维度重塑。同时，还将研究这些技术在评估硬组织和软组织方面的可靠性。研究结果将有助于临床医生更好地理解和预测磨牙区牙齿丧失后的牙槽硬组织和软组织愈合结果，从而影响牙齿康复的临床决策。该项目包括三个主要部分：1. 对磨牙丧失后牙槽愈合模式的系统综述；2. 对因严重牙周炎导致的磨牙区牙齿丧失后植入术可行性的回顾性研究；3. 对第一磨牙拔除后牙槽愈合模式的前瞻性研究。
