“…Possible complications of this technique are the need for removal of the radicular shield, its external exposure (due to mobility of the shield towards the restoration), or internal exposure (due to mobility of the shield toward the oral cavity) with the possibility of infection and bone loss [ 28 ]. In the present study, no implant failures or complications were observed, but this technique is operator-dependent and should be performed by expert surgeons [ 28 , 32 ].…”

“…Nevertheless, a comparison of our results with those published in the literature is complicated due to the lack of published data and the existing disparity regarding methodology and results depending on with which other technique SST is compared [ 48 , 49 ]. According to some authors, SST has similar efficiency to immediate implants without a graft in the prevention of horizontal and vertical bone resorption [ 32 ]. Furthermore, Bramanti et al compared height resorption after three 3 years of follow-up in SST and in immediate implants with bone graft and observed a statistically significant difference between both groups (0.6 mm vs. 1.11 mm, respectively; p < 0.01) [ 52 ].…”

Immediate implant placement protocols after dental extraction have enabled a reduction in surgical phases. This procedure has increased patient satisfaction and similar survival rates to late implant placement procedures. However, placing an implant immediately after dental extraction does not counteract the physiological remodeling of alveolar bone. For this reason, additional surgical techniques have been developed, such as the placement of a connective tissue graft (CTG) or the socket shield technique (SST). Dimensional changes in the peri-implant tissues were observed after placement of immediate implants following the extraction and CTG and/or SST. A total of 26 surgical interventions were carried out in which dimensional change variables of peri-implant tissues were analyzed. The preoperative state and immediate postoperative situation were compared with the situation after one year. Measurements were taken at 3, 5, and 7 mm from the gingival margin and analyzed in this CBCT radiological study (Planmeca Promax 3D). The implant platform was used as a reference point for the measurement of changes in alveolar crest height. One year after performing either of the two techniques (CTG and/or SST), a significant increase in the gingiva thickness and vestibular cortex occurred at 5 mm (0.65 ± 1.16 mm) and 7 mm (0.95 ± 1.45 mm) from the gingival margin. Additionally, an increase in thickness of palatal bone was registered at 3 mm (0.48 ± 0.90 mm). The graft placement group showed an increase in thickness of peri-implant tissue in the vestibular area after one year, although CTG and SST groups were clinically similar. The implementation of SST revealed promising results regarding the buccal thickness of hard and soft tissues after one year. A significant increase in vestibular cortical bone thickness, as well as the overall mucosa thickness and buccal bone at 3 mm from the gingival margin, was observed. A significant reduction in the distance from the bone crest to the platform was detected in both techniques. Both techniques (CTG and SST) are appropriate to provide sufficient volume to peri-implant tissues in the vestibular area of anterior maxillary implants. Some limitations were detected, such as the lack of an aesthetic analysis or small sample size, so results should be interpreted with caution. Future studies are necessary to further evaluate the long-term predictability of these techniques.

Introduction: In the context of tooth extraction and aesthetic care, steps are needed for tooth extraction. Alveolar bone resorption after tooth extraction often leads to situations where the long-term function and esthetic success of dental implant restorations is a challenge. Thus, the Socket shield has been described as an alternative technique to maintain the alveolar ridge in the placement of immediate implants. Objective: Conducted a concise systematic review of key considerations and clinical outcomes of minimally traumatic treatment of tooth extraction and dental implants. Methods: The present study followed a concise systematic review model, following the rules of systematic review – PRISMA. The search strategy was performed in the PubMed, Cochrane Library, Web of Science and Scopus, and Google Scholar databases. The present study was carried out from January to March 2022. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 112 articles were found. A total of 47 articles were fully evaluated and 26 were included in this study. The results suggest that the adjunctive use of connective tissue grafting is not mandatory to achieve successful esthetic results for well-planned immediate implant placement with non-functional immediate provisional restoration in a fresh extraction socket. Still, the success/modified success rate, survival, mean resorption of the oral plate, and patient satisfaction, there were no differences between immediate implants placed with a flap or with an envelope flap of minimal thickness.

Effect of the use of platelet concentrates on new bone formation in alveolar ridge preservation: a systematic review, meta-analysis, and trial sequential analysis

Objectives To investigate the histomorphometric changes occurring in alveolar ridge preservation (ARP) based on the use of different plasma concentrates (PCs) in randomized clinical trials (RCT). There is controversy whether the placement of PCs in ARP is effective in the formation of new bone. Materials and methods A systematic review search was conducted in PubMed, Scopus, Web of Science, and Cochrane Database to answer the PICO question: In patients undergoing tooth extraction followed by ARP, do PCs alone in the post-extraction socket in comparison with spontaneous healing improve new vital bone formation percentage in histomorphometric analysis after more than 10 weeks? The risk of bias was assessed and a meta-analysis was conducted. Results Of 3809 results, 8 studies were considered suitable for inclusion. A total of 255 teeth were extracted in 250 patients. Regarding the PCs used, ARP was performed with platelet- and leukocyte-rich fibrin (L-PRF) in 120 sockets, and with pure platelet-rich plasma (P-PRP) in 31 sockets and 104 sockets were controlled. PCs improved new bone formation in ARP with respect to the spontaneous healing group (SMD = 1.77, 95%C.I. = 1.47–2.06, p-value < 000.1). There were no differences between the different PCs (L-PRF and P-PRP). Conclusion The results of this meta-analysis support the efficacy of the use of PCs in new bone formation in ARP. With respect to the different types of PCs studied, no differences were observed. Clinical relevance When planning implant surgery after tooth extraction, treatment with PCs should be considered for ARP. Any PC increases new bone formation compared to spontaneous healing.
