The presence of black triangles around the dental implant-supported prosthesis and the failure to construct adequate papillae around them bothers dental implantologists. Peri-implant surgical soft tissue management will improve esthetics, function, and implant survival.
To compare the effects of rolled and nonrolled U-shaped flaps combined with a temporary crown in enhancing the soft tissue around dental implants.
Forty patients were included in this study; all patients were operated on by the same maxillofacial surgeon at Al-Iraq specialized dental clinics from January 2019 to January 2020. Patients were divided randomly into two groups: group A: at the second stage of implant surgery, a U-shaped flap without rolling was used in conjunction with temporary crown placement; group B: at the second stage of implant surgery, a U-shaped flap with rolling was used in conjunction with temporary crown placement. Then, the temporary crown was fabricated for both groups and kept in place for one month. Two independent maxillofacial surgeons evaluated all patients two weeks after the cementation of the final zirconia crown for the implant soft tissue esthetic score.
The highest possible score assigned to the mesial papilla (2 scores) was present in 92.5% of the group A patients and only 77.5% of the group B patients. Moreover, we have found that alveolar bone contour is achieved perfectly (2 scores) in 70% of group A patients but only in 32.5% of group B patients.
The U-shaped flap without rolling with a temporary crown is a simple technique. It has good results, especially when there is no severe resorption of the labial bone plate (in canine and premolar areas).
牙种植体支持的修复体周围出现黑色三角以及未能在其周围构建足够的乳头，这困扰着牙种植医生。种植体周围手术软组织管理将改善美观、功能和种植体存留率。
比较翻瓣和未翻瓣的U形瓣联合临时冠在改善牙种植体周围软组织方面的效果。
本研究纳入40例患者；所有患者均于2019年1月至2020年1月在伊拉克专门牙科诊所由同一位颌面外科医生进行手术。患者随机分为两组：A组：在种植手术第二阶段，使用未翻瓣的U形瓣并放置临时冠；B组：在种植手术第二阶段，使用翻瓣的U形瓣并放置临时冠。然后，为两组制作临时冠并佩戴1个月。在最终氧化锆冠粘固后两周，由两名独立的颌面外科医生对所有患者的种植体软组织美学评分进行评估。
A组92.5%的患者近中乳头获得了最高可能评分（2分），而B组仅77.5%的患者获得该评分。此外，我们发现A组70%的患者牙槽骨轮廓达到完美（2分），而B组仅32.5%的患者达到。
未翻瓣的U形瓣联合临时冠是一种简单的技术。它有良好的效果，尤其是在唇侧骨板无严重吸收时（在尖牙和前磨牙区）。
