Tooth shell technique (TST) using autologous dentine is possible with lateral ridge augmentation while avoiding a donor region. This study aimed to clarify whether the use of periodontally compromised teeth (PCT) leads to similar results compared to non-periodontally compromised teeth (NPCT). In this retrospective study, the dentin matrix of 41 patients (PCT: = 19 with 29 implants; NPCT: = 22, with 29 implants) was used for TST. All cases were re-examined. Outcome parameters were biological complications, horizontal hard tissue loss, osseointegration, and the integrity of the buccal lamella. Only in one case in the PCT group, a graft was lost. In three cases, minor complications were identified, including two cases of wound dehiscence and one case of inflammation with suppuration (PCT: = 1, NPCT: = 3). All implants, except the one with the severe complication, were osseointegrated and the integrity of the buccal bone lamella was preserved. Mean difference of the resorption of the crestal width and the buccal lamella did not differ statistically between the two groups. TST using PCT showed results comparable to those of NPCT in terms of complications and graft resorption. Processed dentin matrix from PCT can be used and applied with predictable results for bone grafting, utilizing TST.
自体牙本质的牙壳技术（TST）可在进行颊侧增宽术时避免取自体供区。本研究旨在明确牙周病损牙（PCT）的使用是否与非牙周病损牙（NPCT）相比具有相似的结果。在这项回顾性研究中，41 名患者的牙本质基质（PCT：29 个种植体中有 19 个；NPCT：29 个种植体中有 22 个）被用于 TST。所有病例均重新检查。观察指标为生物并发症、水平向硬组织丧失、骨整合和颊侧板的完整性。仅在 PCT 组的 1 例中出现移植物丢失。在 3 例中发现了轻微并发症，包括 2 例创口裂开和 1 例炎症伴化脓（PCT：1 例，NPCT：3 例）。除严重并发症的种植体外，所有种植体均已骨整合，颊侧骨板的完整性得以保留。两组间颊侧板和牙槽嵴顶宽度吸收的差异无统计学意义。使用 PCT 进行 TST 的结果在并发症和移植物吸收方面与 NPCT 相当。利用 TST，来自 PCT 的处理牙本质基质可用于骨移植，并获得可预测的结果。
