Aesthetics in oral implantology: biological, clinical, surgical, and prosthetic aspects

OBJECTIVES: The aim of this study was to identify a correct clinical, surgical, and prosthetic management of endosseous implants replacing missing teeth in the anterior maxilla, achieving predictable aesthetic outcomes. Placement of immediate post-extraction implants without incisions or flap elevation is one of the surgical treatment options able to improve the healing and regenerative potentials of the fresh socket. MATERIALS: Fifty-five patients (33 men, 22 women), ranging in age from 19 to 57 years (mean 29), were selected for this study. All the patients were not smokers, no bruxers, presented stable soft tissue conditions, an acceptable occlusion, and the absence of pathologies that would contraindicate bone healing. Patients were treated with implants made by 2 manufacturers: Institute Straumann, Walderburg, Switzerland and Friadent, Mannheim, Germany. A total of 87 implants were placed immediately after each failing tooth had been removed. The temporary restoration was placed 3 months after implant placement, and the final restoration was placed 4 months from the surgical procedure. The patients were evaluated clinically and radiographically at implant placement, and 2, 4, 18, and 24 months post-insertion. RESULTS: At 24 months, only 3 implants were lost (2 in male patients;1 in female patient). All of these failed implants did not achieve osseointegration. The overall success rate was 96.6%, with an implant failure rate of 3.4%, all prior to restoration. CONCLUSIONS: The immediate placement in the anterior maxilla fresh extraction sockets without incisions or flaps elevation is a surgical option that can ensure ideal peri-implant tissues healing, preserving the presurgical gingival and bone aspects. For a predictable aesthetic result, the most important aspect seems to be the height and thickness of the buccal bone wall, which remain after immediate placement of the fixture.     

Immediate restoration of implants placed into fresh extraction sockets for single-tooth replacement: a prospective clinical study

The aim of the present clinical study was to evaluate the placement of transmucosal implants into fresh extraction sockets and their immediate restoration with temporary crowns. A series of 22 cases with a 12-month follow-up is presented. Twenty-two patients (15 women and 7 men; mean age 39 years) who needed a single tooth replaced because of vertical or horizontal root fracture, caries, endodontic lesions, or periodontal disease were treated with immediate postextraction implant placement. The implant was then restored with a screw-retained prosthetic restoration within 24 hours. Radiographic assessments were made at baseline and 12 months after implant placement. Clinical parameters, such as plaque score, mucositis score, probing attachment level, mucosal margin position, variation of gingival level, and variation of papilla position, were also measured at baseline and after 12 months of follow-up. At 12 months, no implants had failed. Radiographic examination revealed mean bone resorption of 0.5 mm at 12 months compared to baseline. The mean variation of gingival level, compared to the neighboring teeth, was -0.75 mm. Probing attachment levels were 0.79, 0.45, and 0.54 mm at proximal, buccal, and lingual sites, respectively. The values for the mucosal margin position were 2.9, 2.2, and 2.4 mm at proximal, buccal, and lingual sites, respectively. Regarding variation of papilla position, according to Jemt's index, 27 papillae presented with a score of 2 (61%) and 17 with a score of 3 (39%). An examination of oral hygiene and peri-implant soft tissue conditions at the 12-month follow-up visit revealed an overall frequency of plaque-carrying implant surfaces of 13%. Furthermore, mucositis (score 2) was not observed at any of the peri-implant units. Primary implant stability did not significantly increase over time. The immediate restoration of dental implants placed into fresh extraction sockets was shown to be a safe and predictable procedure. The success rate and radiographic and clinical results were comparable to those obtained following the standard protocol. Within the limits of the present investigation, immediate restoration of single-tooth implants placed in fresh extraction sockets can be considered a valuable option to replace a missing tooth. However, long-term clinical trials are needed to confirm the present results.     

脱细胞真皮基质用于前牙即刻种植扩增角化龈的临床研究

目的研究脱细胞真皮基质用于前牙即刻种植扩增角化龈的临床效果。方法唇侧骨板垂直缺损不超过牙根长度1/3的单颗前牙即刻种植病例20例,拔除患牙即刻种植,利用异种脱细胞真皮基质双层封闭植牙创口,并与周围黏膜加压严密缝合,2～3周拆线,8～12周行冠修复。冠修复后3、6个月,从龈缘高点到膜龈联合线测量种植牙角化龈的宽度,和邻牙及术前角化龈的宽度进行比较,并对种植牙的龈乳头进行美学评价。结果 20颗种植牙的角化龈宽度与种植前相比无明显差异,与相邻牙也无明显差异,膜龈联合线自然;17例种植牙的龈乳头达到Jemt氏分类的2级、3级。种植前,20颗种植牙的角化龈宽度为（4.460±0.220）mm,冠修复后3个月为（4.451±0.245）mm,正常邻牙是（4.410±0.189）mm。冠修复后3个月,种植位点角化龈平均宽度与正常邻牙比较（t=1.283,P=0.215）、与术前比较（t=0.584,P=0.566）,差异均无统计学意义。冠修复后6个月,种植位点角化龈宽度为（4.448±0.223）mm,正常邻牙为（4.404±0.197）mm,种植位点角化龈宽度与正常邻牙比较（t=1.620,P=0.122）、与术前比较（t=1.144,P=0.267）,差异均无统计学意义。结论脱细胞真皮基质可用于前牙即刻种植的创口封闭,能作为屏障膜有效引导骨组织再生,并能很好地保持种植位点的角化龈宽度,龈乳头的美学效果好。     

前牙区即刻种植和延迟种植软硬组织的保存比较：临床研究

目的：即刻种植被广泛认为是可靠而成功率相当高的治疗方法。主要的优点是：1、缩短疗程;2、保存牙槽骨;3、易于确定种植体位置。拔牙后3-12个月牙槽骨吸收程度最明显。拔牙后即刻种植被认为是保留牙槽骨的最好方法,但是有学者认为拔牙植骨后延迟种植对于美学效果更加可靠。我们总结了上颌前牙区即刻种植和延迟种植的两组病例,对其牙槽骨的变化和软组织变化进行追踪和测量。材料方法：组一：即刻种植拔牙前拍摄,不翻瓣拔牙后行即刻种植,种植系统为NobelBiocare Replace或Ankylos。在种植体骨壁之间填塞Bio-Oss骨颗粒和Bio-Gide胶原膜。仔细关闭伤口,以确保初期愈合。术后6个月拍3D锥形束CT,并开始修复（临时或者永久修复）。组二：延迟种植拔牙同时植入Bio-col骨胶原,3个月后行种植体植入,之后6个月开始临时修复。种植体植入后6个月拍摄3D锥形束CT。结果：通过3DCT观察,两组患者的牙槽骨都得到了比较好的保存,牙龈的边缘水平和牙龈乳头的高度都比较理想。第二组患者在拔牙后和种植后牙龈乳头变圆钝,有不同程度的萎缩现象,但是在临时修复后3个月出现自动恢复的现象。结论：两组患者都显示出美学效果良好,说明这两种方法都可以比较可靠地达到良好的美学效果。即刻种植更显示出缩短疗程的优势;而延迟种植需要更长的治疗时间。我们建议在前牙即刻种植或延迟种植时使用引导骨再生技术,同时使用移植骨材料和隔离膜。在组织稳定性和美学效果的稳定性方面还需要长期的前瞻性临床观察。

??Objective    To compare the changes of the periimplant papilla index and labial gingiva fullness between flap and flapless immediate implant placement after reshaping the perimplant soft tissue using implant supported provisional prostheses. Methods    From August 2007 to March 2011??41 patients were enrolled in Department of Implant Dentistry??School and Hospital of Stomatology??Peking University. The patients were classified into two groups. Group ??immediate implant using flapless technique and Bio-Oss Collagen in 20 cases. Group ??immediate implant placement using guided bone regeneration??GBR??after flap reflection in 21 cases. All the patients underwent sequential gingival architecture remodeling using implant-supported temporary prostheses. Marginal bone resorption after loading of 1 and 3 years were measured and statistical analysis was conducted. Esthetic evaluations included papilla index and the labial gingiva peri-implant soft tissue fullness. Results    Totally 41 implants were placed in 41 cases with ReplaceSpeedy® implants. The mean follow-up was 42.4 months??24-67 months??and no implant was lost until the last recall. One and three years after final restoration delivered?? papilla index and labial gingiva fullness were compared between two groups and no significance was observed ??P > 0.05??. After 1 and 3 years??marginal bone resorption was??0.50 ± 0.04??mm and??0.55 ± 0.04??mm in flapless group????0.59 ± 0.03??mm and??0.67 ± 0.03??mm in flap group respectively??and statistical significance was observed between two groups??P < 0.05??. Patients’ satisfaction was high in both groups and treatment comfort was higher in flapless group. Conclusion    The clinical results and gingival stability is predictable in choosing flap or flapless immediate implant technique in the maxillary anterior teeth when proper indication and technique are selected. Using implant supported provisional prostheses can reshape and stabilize periimplant soft tissue and the short-term results are predictable. Marginal bone level was stable and less bone resorption was founded in flapless group compared with flap group. Patients in both groups were satisfied with the clinical results and treatment comfort and flapless group had higher patient satisfaction.
