Filter by:An interventional prospective randomised clinical trial (RCT) in parallel groups is planned. The sample size was 30 patients who will be randomly divided into two groups based on the surgical procedure. The first group is the healing of the donor zone after SCTG harvesting without filling the wound with collagen matrix. The second group is the wound defect closure in the donor area using the collagen matrix "FibroMATRIX" (LLC "Cardioplant", Russia; registration in Russia 20/05/2019 No FSZ 2019/83671). Changes in volumetric parameters of the maxillary tuberosity area after CTG harvesting, severity of pain, postoperative edema, bleeding, analgesic intake and quality of life in the postoperative period will be assessed.
This was an interventional prospective randomized clinical trial (RCT) in parallel groups. The sample size is 32 patients who were randomly divided into two groups depending on the surgical intervention used. First group - patients underwent increasing the thickness of the mucous membrane using free connective tissue graft from tuberosity area of the upper jaw. Second group - patients used collagen matrix Fibro-Gide" (Geistlich Pharma AG, Bahnhofstrasse 40, 6110 Wolhusen, Switzerland; registration in Russia 19.08.2020 No FSZ -20207/11765). In the postoperative period the value of soft tissue thickness gain, severity of pain, collateral edema, amount of analgesics consumed, soft tissue aesthetics, keratinized mucosa width, quality of life and duration of surgery were assessed.
This is an interventional prospective randomized clinical trial (RCT) in parallel groups. This study is aimed at detecting a difference in the increase in the thickness of soft tissues of at least 0.3 mm between the two groups (the standard deviation [SD] of 0.3 mm and the average value of 1.2 mm was borrowed from an article published by Cairo F et al., 2017). Using SampleSizeCalculator, it was calculated that the number of patients in each group should be 14 (alpha = 0.05; power = 80%). This number was increased by 10%, taking into account possible exceptions from the study. The sample size is 30 patients who will be randomly divided into two groups depending on the surgical intervention used. First group - patients will undergo increasing the thickness of the mucous membrane using free connective tissue graft from tuberosity area of the maxilla or palate. Second group - patients will undergo increasing the thickness of the mucous membrane using collagen matrix "Fibro-Gide" (Geistlich Pharma AG, Bahnhofstrasse 40, 6110 Wolhusen, Switzerland; registration in Russia 19.08.2020 No FSZ-20207/11765). In the postoperative period the value of soft tissue thickness gain, severity of pain syndrome, collateral edema, Doppler flowmetry, probing depth, soft tissue aesthetics, keratinized mucosa width and quality of life will be assessed. In addition, after 3 months simultaneously with installation of gingiva formers biopsy specimens will be sampled with mucotome in the area of the intervention followed by histomorphometric analysis of the obtained biopsies.
This was an interventional prospective randomized clinical trial (RCT) in parallel groups. The sample size is 35 patients who were randomly divided into two groups depending on the surgical intervention used. First group - patients underwent increasing the thickness of the mucous membrane using free connective tissue graft from tuberosity area of the upper jaw. Second group - patients used collagen matrix "Fibromatrix" (LLC "Cardioplant", Russia; registration in Russia 20/05/2019 No FSZ 2019/83671). In the postoperative period the value of soft tissue thickness gain, duration of surgery, severity of pain syndrome and quality of life were assessed. Also, after 3 months simultaneously with installation of gingiva formers biopsy specimens were sampled with mucotome in the area of the intervention followed by histomorphometric analysis of the obtained biopsies.
The purpose of the study is to compare soft tissue volume changes in terms of volume gain and stability around dental implants and PROMS in cases where a sub-epithelial connective tissue graft (SCTG) from the palate, Porcine collagen matrix (CM) or Porcine Acellular dermal matrix (PADM) is used after 3 and 15 months after implant placement.
fixation of FGG with sutures alone is not sufficient,we use cyanoacrylate beside sutures for fixation
