Nevertheless both types of prosthetic treatment inhere major gingival aesthetic pitfalls by physiological vertical and horizontal resorption. Aim of the study was to investigate if the immediate insertion of root analogue single-stage implants and prosthetic treatment could prevent gingival recessions and bone resorption thus keeping the natural gingival aesthetics untouched. Between 2003 and 2006, 348 root analogue Q1-Implants (TRINON Karlsruhe GmbH/Germany) were inserted in 342 patients’s premolar and molar regions immediately after tooth extraction or traumatic tooth loss and treated with provisional resin crowns. The observation period with recurring 6-month clinical and radiographic check-ups was a minimum of 5 years. Of 348 inserted implants 4 (1.15%) were lost resulting in an overall success rate of 98.85%. In the first 12 weeks after surgery a mean recession of the buccal gingival margin of 0.2 mm (SD 0.34) could be detected, after final prosthetic treatment an overall mean recession of 0.2 mm (SD 0.13) within the survey period. Immediate implant insertion of root analogue single stage implants and immediate prosthetic treatment with provisional resin crowns after minimal invasive tooth extraction seems to be appropriate to prevent bone resorptions of the buccal alveolar crest and the recessions of the gingiva and papillae and thus suggests to be the preferable treatment to keep the natural gingival and papillary aesthetics untouched preventing further traumatic surgical gingival reconstructions.展开更多

文摘目的：观察置骨法重塑种植牙牙间乳头的稳定性,探讨种植牙牙间乳头重塑的可行性方法。方法：选取102例牙周骨质较好、两颗及以上连续缺失的种植病例,分成两组,每组51例。置骨组在植入种植体时,其顶部高于骨皮质0.51.0 mm。在种植体之间的骨皮质处打微细滋养孔,取邻近牙槽骨或回收自体骨与Bio-oss骨粉混合,置于种植体间和唇侧牙龈不饱满处,将Bio-Gide膜剪孔,严密覆盖种植体周围,固定。将龈瓣以L型转瓣分别缝于种植体间,或者在种植同期用＂split-finger＂技术恢复重建龈乳头。共修复种植体间乳头76个。另一组则在完成常规种植体植入后,将牙龈转瓣缝合,在唇侧不饱满处,取上腭黏膜垫入。共修复种植体间乳头67个。在12个月时分别测定两组牙龈乳头指数（papilla index score,PIS）和主观美观指数以及种植体周围袋的深度,进行比较。结果：置骨组种植体间乳头的PIS 3级（P〈0.01）和主观美观指数Ⅰ级数量（P〈0.05）明显高于常规组。置骨组比常规组更能达到最佳的龈乳头修复。结论：置骨法重塑种植体牙间乳头,在多颗种植牙时有一定的应用价值。
