Filter by:A clinical Trial, comparing two different techniques to elevate the maxillary sinus floor membrane to allow for simultaneous dental implant placement in the severely atrophied maxillary ridges.Both using allogenic bone substitute as the bone graft material. One technique is the open lateral window technique and the second is the closed crestal technique.
The aim of the study was to compare efficacy of autogenous onlay and inlay grafts for anterior maxillary horizontal ridge augmentation.
This study aims to evaluate the clinical and radiographic outcomes of different staged ridge-splitting techniques for management of severely resorbed lower jaws in the posterior region. The study is designed as a clinical trial, so that three different interventions would be compared for a conclusion highlighting the relative best of them.
The goal of this clinical study is to investigate the effectiveness of the split-box technique in systemically healthy, non-smoking, over 18 years of age, participants with narrow crests (<5mm bone width) and adequate bone height (>12mm). The main questions it aims to answer are: - The primary objective of the present study is to investigate the effectiveness of the split-box technique by evaluating the change in width and height of the alveolar bone. - The secondary objective is to evaluate the superiority of the split-box technique and its modifications in terms of the amount of bone gain. According to the 3D topography of the alveolar ridge of the patients before augmentation, split box or one of its modifications, reverse split box or sliding split box techniques were selected and applied. (split box was applied if the bone thickness was more than 3 mm at the top of the crest and did not increase towards the lower border at the alveolar bone, reverse split box technique was applied if the bone thickness was more than 3 mm at the top of the crest and increased towards the lower border at the alveolar bone, sliding split box was applied if the bone thickness was less than 3 mm at the top of the crest but the bone thickness increases towards the lower border at the alveolar bone.)
The viability of Platelet Rich Fibrin (PRF) on enhancement of osseous and associated tissue healing has been substantiated well in literature. This study aimed to assess peri-implant soft and hard tissue changes after prosthetic loading of implants following socket preservation with platelet-rich fibrin (PRF) and freeze-dried bone allograft (FDBA) in a 12-month period. This Study evaluated 48 patients who were randomly divided into two groups for anterior ridge preservation with PRF and FDBA. At 12 months after implant placement and prosthetic delivery, bone loss was evaluated radiographically while soft tissue changes were evaluated by measuring gingival recession, papilla index, and bleeding on probing (BOP). The differences between the PRF and FDBA groups were analyzed using Fisher's exact test and student's t-test (P<0.05).
Clinicians are increasingly faced with the challenge of reconstructing the alveolar ridge as more patients desire fixed implant-supported restorations. Reconstruction of large horizontal alveolar defects still remains a challenge in implantology. Although autogenous blocks from intraoral sites are proven effective for such defects, donor site morbidity and limited graft availability are major limitations. Allogenic bone blocks have been proposed to overcome these limitations, however, the outcomes reported in the literature are inconclusive. In this case series, the efficacy of allogenic blocks for lateral augmentation of atrophic ridges was evaluated, over a three-year period. In nineteen edentulous sites from ten patients, cortico-cancellous allogenic blocks (PHOENIX, TBF, France) were shaped to the defect and screw-fixated. A double-layer of autogenous chips and demineralized bovine bone (Bio-Oss, Geistlich Pharma AG, Switzerland) was used to fill the voids. The augmented site was covered by non-cross-linked collagen membrane (Bio-Gide, Geistlich Pharma AG, Switzerland). After a healing period of 9 months, implants were placed and CBCT analysis was performed post-implantation. Following a period of 34 months of function (range 22 to 44 months), patients were clinically and radiographically re-examined.
This study will evaluate the effect of allograft bone particle size on the bone quantity and quality following socket grafting and lateral ridge augmentation in preparation for endosseous implant placement. Pre (baseline)- and post-grafting (3 months for sockets and 6 months for edentulous ridges) clinical as well as 2- and 3-dimensional radiographic measurements will be used to evaluate the differences between sites grafted with small vs. large particle sized bone allografts. Histological analysis will be performed at time of surgical re-entry of grafted sites to place the dental implants, and assessed for differences in new bone formation between the 2 types of grafts.
This randomized controlled split-mouth clinical trial study was designed to evaluate the effects of low-level laser therapy on bone healing in patients with bilateral sinus lifting and simultaneous dental implant application. Maxillary posterior partially edentulous or totally edentulous twelve patients who need bilateral sinus bone augmentation were included in this study. Sinus bone augmentation and dental implant surgeries were done simultaneously. Low level laser therapy (LLLT) was (λ= 630-660 nm, 25 mw / cm², 6 mins) applied for just one operation side at first, third, fifth and seventh days. Treatment side were randomly selected by another surgeon who applied LLLT. Panoramic radiographs were taken at the first, third and sixth months using aluminum step-wedge technique. Optic Density analyses were performed using Cardinal Health Digital Densitometer (Fluke Biomedical 07-443) with 1mm diameter. Digital densitometric results were obtained as equivalent aluminum thickness for each radiograph. These data were used to evaluate changes in optical bone densitometry and compare the LLLT applied side and control side for each patient.
This study is designed to compare the clinical and histologic results of ridge augmentation with and without primary closure over the barrier membrane. The hypothesis is that there will be no difference in crestal ridge width between the two groups.
