“…Previous studies have similarly reported a more apical crestal bone level with the open flap technique than with the flapless technique (Bashutski et al, ). Other studies have reported comparable levels of crestal bone around healed sites with flap and flapless techniques (Vohra, Al‐Kheraif, Almas, & Javed, ). Nevertheless, flap elevation does not seem to enhance the risk of increased bone levels, and there is a trend towards better results using a flapless approach.…”

Objectives To assess through cone‐beam computed tomography (CBCT) buccal alveolar bone alterations after immediate implant placement using the following techniques: open flap and grafting (flap‐graft), open flap and no grafting (flap‐nograft) and flapless and no grafting (noflap‐nograft). Materials and methods This was a three‐armed parallel group randomized clinical trial with allocation ratio 1:1:1. Patients were eligible in case they needed immediate implant replacing teeth in maxillary premolar area, with sufficient buccal bone support. CBCT was performed immediately after the intervention and 6 months later. The main outcomes were CBCT measurements performed at apical (A‐EA), medial (M‐EM) and external and internal implant bevel level (B‐EB, B‐IB) and vertical defect depth (DP). Pain and discomfort, time of surgery and complications were recorded. Differences between groups were estimated through ANOVA tests and post‐hoc Scheffe's analysis for pairwise comparisons. Multiple regressions were conducted to estimate influence of gingival biotype and baseline marginal gap dimension. Results Forty‐five patients were recruited and randomized to treatments with one lost to follow‐up. Analysis of variance showed that the effect of treatment technique was not relevant for all horizontal and vertical outcomes. The three techniques exhibited almost complete fill of marginal gap, with a mean residual vertical gap of 0.27 mm and horizontal gap of 0.5 mm. Regression models indicated a positive effect of thick biotype on gap filling and dimensional bone reduction. The noflap‐nograft technique resulted less painful. Conclusions The option of noflap‐nograft surgery in post‐extraction implants allows for minimal surgical intervention with comparable buccal bone changes and gap filling after a follow‐up of 6 months in sites with sufficient buccal bone support.

“…20 Another hypothesis could be the higher number of implants from the flapless surgical technique placed in the posterior regions, where softer bone is present and usually submitted to high occlusal loads, which can influence the loss of bone; however, the advantages in postoperative conditions might suggest a favorable risk-benefit ratio for the flapless surgical technique: A systematic review 8 investigating the management of soft tissues reported that dental implants placed with a flapless technique induced statistically less postoperative pain when compared to dental implants inserted using flap elevation. Furthermore, according to another systematic review, 21 the crestal bone loss was comparable between dental implants placed in healed sites using flap or flapless techniques.…”

Partial edentulism rehabilitation through immediate provisionalization fixed prosthesis supported by dental implants inserted through flap or flapless surgical techniques in areas of predominantly soft bone was viable at 3 years of follow-up. The limitations and risks of the "free-hand" method in flapless surgery should be considered when planning implant-supported fixed prosthetic reconstructions.
