It is well known that wound dehiscence is one of the most frequent complications in guided bone regeneration. The main cause of this complication may be a lack of tension-free and primary wound closure. The aim of this study was to evaluate and compare the effect of periosteal releasing incisions (PRI) upon the extension of three different flap designs: envelope, triangular and trapezoidal flaps. Twelve pig mandibles were used to quantify extension of the flap designs. The mandibles were equally and randomly distributed into the three flap groups. Each mandible was divided into two sides: one was subjected to a PRI and the other not. The flap was pulled with a force of 1.08 N and the extension was recorded. The subgroups without PRI showed an average extension of 5.14 mm, with no statistically significant differences among them (p = 0.165). The PRI provided an average extension of 7.37 mm with statistically significant differences among the subgroups (p < 0.001). The releasing incisions significantly increased flap extension in each flap design. The increase in extension of the trapezoidal flap with PRI was significantly greater than in the other subgroups. In cases where primary closure is required, surgeons should consider performing trapezoidal flaps with PRI in order to reduce tension.

Background. Bone augmentation ensures a favorable 3-dimensional position of implants. Onlay grafting is one of the techniques in ridge augmentation, which can be performed with the use of xenogenous blocks. Methods. Three cases of the vertical and horizontal ridge are discussed, which were augmented using xenogenous blocks. The blocks were shaped in a favorable size and puzzled along the grafting area. All the gaps were filled with granular xenografts. The flaps were coronally advanced to obtain primary closure. Results. An average of 4.2-mm gain in width and 4.2-mm gain in height of the ridge was observed at the implantation stage. Conclusion. The outcomes of these cases could pave the way for suggesting xenograft blocks for augmenting wide areas of the alveolar ridge on average of 4 mm in width and height in selected cases as an alternative to standard autogenous blocks. Long-lasting xenograft ensures implant and lip support in the esthetic zone.

Membrane fixation in guided bone regeneration (GBR) has been traditionally achieved using resorbable pins, titanium tacks or miniscrews. However, these techniques are marredwith a number of clinical challenges. This article presents the “SauFRa” technique, a novel technique for stabilization of resorbable membranes in both, single as well as multiple implant sites while avoiding the shortcomings of other suturing techniques described in literature. Furthermore, the technique also eliminates the possibility of complications observed when using resorbable pins, titanium tacks or miniscrews, such as damage to adjacent roots during insertion. The authors’ employed this technique in 89 patients (51 male and 35 female) and found no complications like tissue dehiscence, infection or graft migration.
