Three‐dimensional analysis of dimensional changes after alveolar ridge preservation with bone substitutes or plasma rich in growth factors: Randomized and controlled clinical trial

Abstract

Objectives To evaluate alveolar ridge dimensional changes of different alveolar ridge preservation techniques after 3 months of tooth extraction and to compare the efficacy of autologous plasma rich in growth factor (PRGF) to the bone substitutes in alveolar ridge preservation and sites left to heal spontaneously. Materials and Methods Forty patients requiring tooth extraction in the anterior maxilla were randomly allocated to the four following treatment modalities: spontaneous healing (control), natural bovine bone mineral covered with resorbable native collagen membrane (BBM/CM), freeze‐dried bone allograft covered with resorbable native collagen membrane (FDBA/CM) and PRGF alone. Cone beam computed tomography (CBCT) scans were taken after surgery and 3 months later. The measurements of height and width (at 1, 3, and 5 mm below the crest) were performed after superimposing the 2 consecutive CBCT scans. Results The greatest horizontal alveolar bone resorption at 1 mm below bone crest was observed in the control group (−1.61 ± 1.76 mm, P = .037), whereas the least reduction in width was found in the BBM/CM group (−0.68 ± 0.67 mm, P = .037). The most pronounced alveolar height reduction was observed in the control group (−0.86 ± 0.43 mm), whereas alveolar ridge preservation with BBMC/CM (−0.26 ± 0.91 mm) and PRGF (−0.54 ± 0.86 mm) successfully reduced the alveolar height reduction as compared to the control group. Conclusions Alveolar ridge preservation technique in the esthetic zone using BBM/CM or using PRGF is beneficial to reduce horizontal and vertical bone changes.

The impact of autologous concentrated growth factors on the alveolar ridge preservation after posterior tooth extraction: A prospective, randomized controlled clinical trial

“…Our results were in line with these findings, with a value of 1.49 mm in the control group and 0.63 mm in the experimental group. The similar results were showed in the RCT of PRGF compared with bone graft materials 46 . The low value in our study may be attributable to differences in study inclusion criteria, although further work is required to fully understand any potential differences between these analyses.…”

Use of fan beam computerized tomography and cone beam computerized tomography in oral and maxillofacial surgery and its indications: A literature review

“…Cone-beam computed tomography emerged in the late 1990s, when the overlap found in two-dimensional radiographic examinations made it difficult to visualize deeper structures 5 . In this way, the technology brought the X-ray beam is projected conically at a fixed point, with the formation of several images segmented in cuts in the three-dimensional planes [12,15], allowing the detailed anatomical visualization, in addition to the optimization of the visual resources of the image and its spatial manipulation [5].…”

“…In this regard, it is necessary to identify ideal situations for the use of cone beam or fan beam techniques, knowing the specific indication for each one and its applicability, its advantages and disadvantages [14,15,16,17], in addition to a comparison between Cone Beam Computed Tomography and Spiral Computed Tomography in the field of dentistry regarding Oral and Maxillofacial Surgery and Traumatology [9].…”

Autologous Platelet Gel (APG): A Preliminary Evaluation of the Mechanical Properties after Activation with Autologous Thrombin and Calcium Chloride

“…Today there is great interest in autologous platelet gel, platelet concentrates (PC), and growth factors. They are extensively used in endodontic [ 17 ], oral surgery, in implantology [ 18 ] and parodontology [ 19 ]. Platelet concentrates (PC) have been widely used in bone regenerative procedures for their autologous origin and they offer a great concentration of platelets, when compared to the concentration in natural blood.…”
