“…The absence of a filler material can contribute to shortening of the marginal gingival margin compromising the aesthetics in immediate implants, especially in the aesthetic region. Therefore, it is suggested that less resorption appears when the space is filled with a low resorption biomaterial, such as bovine bone [4]. Other studies show the same, while grafting extraction sockets does not prevent alveolar bone remodeling, it does minimize buccal bone collapse [17,18].…”

“…The 1-phase patients received a healing abutment since esthetics was not important for them, and a Bioplug (4) was used to cover the buccal gap. The 2-phase patients received a Osseoguard flex (2) completely covering the implant and extraction site.…”

“…Most changes in ridge contours happen during the first 12 months post-extraction were predominantly horizontal and more pronounced buccally then lingually [3]. The buccal bone plate is more suspectable to resorption then the lingual plate, due to its thickness [4] . CT scan in 250 patients have showed anterior facial plate thickness ranges from 0.3-1mm with about 50% of the wall thickness is less than 0.5 mm.…”

“…THE OPEN HEALING TECHNIQUE AND TISSUE LEVEL IMPLANTS favorable outcomes for crestal bone level changes, the small differences may not be clinically relevant because of high heterogeneity among studies [8]. However, the use of immediate implantation techniques without raising a muco-periosteal flap, combined with a bone graft in the gap left between the implant and the post extraction socket walls, led to osseointegration accompanied by high stability of bone and the resulted soft tissue [7][8][9]. On the other hand, the use of tissue level implants is beneficial for the surrounding soft and hard tissues, especially when inserted with a flapless approach.…”

“…It has been previously reported [6] that immediate implantation will not prevent resorption of the alveolar ridge. A recent systematic review analyzed the three-dimensional changes in bone tissue after immediate installation of a single implant in a fresh extraction socket, reaching a clear conclusion that bone remodeling occurs after tooth extraction even with immediate implant insertion [7]. One other recent systematic review described the effects of implants with different connections on the crestal bone level in relation with the surgical procedure after at least 12 months of functional loading.…”

Introduction: Correctly managed, immediate implant placement into fresh extraction socket is a favorable treatment option in order to reduce the overall treatment time and to increase the patient's comfort and satisfaction. Methodology: Atraumatic extractions (N = 42) with socket preservation were performed in n = 40 patients (0.74 sex ratio) followed by immediate placement of tissue level implants. Post extraction sockets were filled with either platelet-rich growth factors (PRGF) clots, or deproteinized bovine bone granules, or both; then covered by collagen resorbable membrane or cyanoacrylate and left exposed during healing. The pre-loading need for additional augmentation was assessed clinically and radiologically, using CBCT scans at t = 6 months. The success and survival rate were evaluated by control CBCT scans at a 4 year follow-up. Results: This analysis showed that "open healing" technique allowed uneventful healing and sufficient bone formation in combination with immediate placement of soft tissue level implants, a survival rate of 100% and a success rate of 95.2% at a 4 yr follow-up. There were no significant differences regarding crestal bone level stability around the implants with the different augmentation materials. Conclusion: Immediate placement of tissue level implants in fresh post extraction sockets using "open healing" approach can be favorable from both a clinical and radiological point of view considering the results at 4 years. In addition, soft-tissue problems associated with extensive flap mobilization and tension may be avoided and the 3D architecture of hard and soft tissues surrounding the implant may be maintained due to the tissue level implants design in accordance with the biological width when restored.

Background: Flapless immediate implant placement and provisionalization (FIIPP) in the aesthetic zone is still controversial. Especially, an initial buccal crest thickness (BCT) of ≤1 mm is thought to be disruptive for the final buccal crest stability jeopardizing the aesthetic outcome.Purpose: To radiographically assess the BCT and buccal crest height (BCH) after 1 year and to calculate the correlation between initial and final achieved BCT. Materials and Methods:The study was designed as a prospective study on FIIPP.Only patients were included in whom one maxillary incisor was considered as lost. In six centers, 100 consecutive patients received FIIPP. Implants were placed in a maximal palatal position of the socket, thereby creating a buccal space of at least 2 mm, which was subsequently filled with a bovine bone substitute. Files of preoperative (T0), peroperative (T1) and 1-year postoperative (T3) cone beam computed tomogram (CBCT) scans were imported into the Maxillim™ software to analyze the changes in BCT-BCH over time.Results: Preoperatively, 85% of the cases showed a BCT ≤1 mm, in 25% of the patients also a small buccal defect (≤5 mm) was present. Mean BCT at the level of the implant-shoulder increased from 0.6 mm at baseline to 3.3 mm immediate postoperatively and compacted to 2.4 mm after 1 year. Mean BCH improved from 0.7 to 3.1 mm peroperatively, and resorbed to 1.7 mm after 1 year. The Pearson correlation of 0.38 between initial and final BCT was significant (p = 0.01) and therefore is valued as moderate. If only patients (75%) with an intact alveolus were included in the analysis, still a "moderate correlation" of 0.32 (p = 0.01) was calculated.Conclusions: A "moderate correlation" was shown for the hypothesis that "thinner preoperative BCT's deliver thinner BCT's" 1 year after performing FIIPP.
