Clinical evidence suggests using lateral and vertical ridge preservation procedures to make dental implant placement possible. This study evaluates and compares the radiographic and volumetric changes following ridge preservation procedures using either mineralized plasmatic matrix grafts (MPM) or bone grafts alone (non-MPM) in the existing crestal ridges of sockets in maxillary and mandibular regions using CBCT scans. Healthy volunteers (n = 26) were recruited and randomized into MPM and non-MPM groups (n = 13 patients per group). Ridge preservation (RP) was performed in sockets after extraction. Preoperative baseline vertical measurements (V1) were made from the existing highest level of the socket crestal ridges to a reference point in an apicocoronal direction. Similarly, baseline horizontal measurements (H1) were made in a buccolingual direction on CBCT scans. The measurements were repeated after 3 months (V2 and H2) and 6 months (V3 and H3) using the same reference points. Difference between V3 and V1 as well as H3 and H1 was used to assess the gains in height and width of the sockets after RP. No significant difference was found in the initial baseline V1 and H1 values in MPM and non-MPM groups. Median (Mdn) V2 and H2 scores were significantly different between MPM (Mdn = 18.91) and non-MPM groups (Mdn = 27.81) after 3 months of RP (U = 37, z = -6.302, P less then .001.) However, after 6 months of treatment, V3 and H3 scores were significantly different between the MPM (Mdn = 27.19) and the non-MPM group (Mdn = 37.81). MPM can be used as a valuable and predictable technique in obtaining bone fill in the maxillary and mandibular sockets with residual crestal ridges deemed necessary for RP in implant therapy.Retrograde peri-implantitis (RPI) is a periapical lesion that develops after implant insertion in which the coronal portion of the implant achieves a normal bone-to-implant interface. The most common etiology of RPI is the presence of an adjacent endodontic lesion. In most of the case reports available in the literature, the diagnosis of RPI occurred between 1 week and 4 years after implant placement. This case report illustrates the treatment of RPI that occurred more than 15 years after implant loading, caused by endodontic infection of the adjacent tooth.The aim of this retrospective study was to evaluate the long-term performance of the supercritical CO2 (Supercrit, BIOBank) viral-inactivated bone allografts in maxillary sinus augmentation. Thirty-four consecutive patients underwent 50 maxillary sinus augmentation procedures, and 103 implants were placed. At a mean of 8.8 years after graft surgery, 95 implants were well osseointegrated and functioning. Eight implants failed, and the overall implant survival rate at 10 years was 92.2%. The marginal bone loss averaged 1.2 ± 1.3 mm. Within the limitations of this study, the supercritical CO2 viral-inactivated bone allograft is a valuable bone graft material, achieving long-term satisfying outcomes when used alone.This prospective controlled clinical trial investigated the possible correlation among mucosa thickness, mucosa height, and width of keratinized mucosa on the contour changes of the peri-implant soft tissue collar over a period of 12 months. Forty patients were selected to undergo implant placement. https://www.selleckchem.com/products/apr-246-prima-1met.html Impressions were taken with polyether impression material at delivery of the final restorations (baseline) and at 1, 3, 6, and 12 months. Master casts were fabricated and scanned using an indirect digitalization. Baseline and corresponding follow-up scans were then virtually superimposed and matched. At 1 year, 20 patients who received the buccal pedicle flap showed an average thickness increase of 1.49 mm (ρs = 0.95; range 0.01 to 2.56 mm), whereas the 5 patients who received a connective tissue graft at second-stage surgery reported an average thickness increase of 0.33 mm (ρs = 0.70; range -0.62 to 1.23 mm). Finally, the remaining 15 patients who did not receive any soft tissue grafting nor any type of plastic surgery showed an average mucosa thickness increase of 0.51 mm (ρs = 0.28; range -2.33 to 2.52 mm).The aim of the present study was to evaluate the efficacy of alveolar ridge preservation (ARP) protocol using deproteinized bovine bone mineral (DBBM) covered with a collagen matrix (CM), as well as to clinically and histologically analyze the alveolar bone healing at 12 months, prior to implant placement. Six patients had bone biopsy samples harvested and underwent implant placement at 12 months following ARP. At 12 months, DBBM granules represented a mean 29.52% ± 6.09% of the specimens and were embedded in the newly formed bone, which represented a mean 27.72% ± 5.64% of the sample. Data suggest that 12 months of ARP using DBBM granules covered with a CM may be considered a predictable technique providing favorable conditions for implant placement in the anterior maxilla.In dental implant surgery, bone grafts are used for the reconstruction and reestablishment of alveolar bone volume and to improve bone architecture for better positioning of an implant. The present report describes the use of the bone ring technique for vertical and horizontal bone augmentation with simultaneous implant placement. This is a simple technique for acquiring donor bone in a ring shape and performing 3D reconstruction of bone defects, with an increase in the alveolar crest, using autogenous bone in a surgical procedure together with implant placement. Block bone grafts taken from the mentum can be used for predictable bone augmentation of up to 6 mm in the horizontal and vertical dimensions. The thickness of the bone ring collected from the mentum is very important. It cannot be too thin due to the risk of fracture, nor can it be too thick, as its contour could become deformed when placed in the receptor site. For stabilization and synthesis, a horizontal mattress suture is performed at the receptor site without promoting tension, and simple sutures are used for the complete co-optation of the flap and consequent stabilization of the clot. In the present type of bone defect, single-stage implant placement may be useful to shorten the overall treatment period.
