Filter by:Forty patients ( 24female and16 male )with completely edentulous maxilla and mandible . All patients received implant supported mandibular and maxillary overdentures. The patients were randomly divided into two groups according to attachments retaining Max IOD that supported by four axial implants in maxilla . The TA was used to retain group I (GrI) MaxIOD , while that of group II (Gr II) was retained by LA. MaxIOD retention and MBL(vertical and horizontal) around implants of both groups was recorded at time of insertion (R0) ,then twelve(R12)and (R24) months following insertion of the prosthesis.
Fourteen completely edentulous patients were selected to participate in this study. From the outpatient clinic of Prosthodontic Department, Faculty of Dentistry, Ain Shams University. After fabrication of complete denture for all patients, patients were randomly divided to: Group A: Seven patients were rehabilitated with implant retained maxillary overdenture where four Straumann BLX® implant were inserted opposed by mandibular complete denture. Group B: Seven patients were rehabilitated with implant retained maxillary overdenture where four conventional acid etched implants were inserted opposed by mandibular complete denture. After implant placement using surgical guide, smart peg and ostell device were used to measure the primary stability of the implant then cover screw was placed and after six weeks, secondary stability was measured for both groups. After four months, the second stage started in which exposure of the implant fixtures took place and pick up was carried out. Patients were recalled frequently for post-insertion inspection and adjustment.
Our study looks into how the thickness of the gum tissue affects the health of the bone around dental implants over ten years. We include 59 people and divide them into three groups based on their gum tissue thickness. Some have naturally thin gums, some have thin gums that were made thicker with a special procedure, and some already had thick gums. We try to find out if having thicker gums, whether naturally or through enhancement, can help keep the bone around dental implants healthy in the long run.
The goal of this split-mouth randomized clinical trial study was to investigate the effect of using a laser on pain and discomfort following flapless dental implant surgery. It was hypothesized that laser did not have any impact on post-op pain. Therefore, the study aimed to compare pain and discomfort following flapless dental implant surgeries with or without a laser.
The dental implant placed freehand with a digital planing is vastly increasing. The accuracy between the planned and the placed implants still not well determined. Between a single implant and a full mouth rehabilitation, the precision is very wide. A precision scale must be settled according to each indication in order to offer the clinician a safety and a predictability for his procedures.
The goal of this randomized clinical trial is to compare and assess the prosthetic maintenance of two implant-retained mandibular overdentures reinforced with PEKK and Co-Cr frameworks after twelve months. Twenty-four participants were randomly assigned to two groups: Group I received a mandibular implant-retained overdenture reinforced with a Co-Cr framework, while Group II received a mandibular implant-retained overdenture reinforced with a PEKK framework. Also, both groups were rehabilitated with a maxillary complete removable denture.
The present randomized controlled trial aims to assess the influence of a new prosthodontics device (Gingival Former Abutment -GFA) on peri-implant bone loss and soft tissue changes and health after subcrestal oral implant placement. The participants will be divided in two groups and receive either crestal implant placement and traditional healing abutment or subcrestal implant placement and GFA. Clinical and radiographic examination will be performed at implant placement surgery, prosthetic load, 6 and 12 months follow-up.
The aim is to clinically and radiographically assess a novel wedge implant placed in narrow ridges. - 60 wedge implants (Rex Implants, Columbus, OH, USA) will be placed using Piezosurgery® following either a bone consumption (n=30) or bone expansion technique (n=30). Each group (bone consumption and bone expansion) will be divided into 2 surface treatments: machined transcortical portion (n=15) and roughened transcortical portion (n=15). - Record the time needed to place each implant. - ISQ will be evaluated at Day 0, 3 weeks, 6 weeks, 3 months, 4 months, and 6 months after implant placement. - Periapical radiographs will be performed at implant placement, loading. and 1, 3, and 5 years after loading to assess marginal bone stability. - Buccal bone height and lingual and buccal bone thickness will be recorded post-intervention, at the time of functional loading, and at 12, 36, and 60 months after loading with CBCT. - Digital impressions will be taken post-operatively, at loading and at 12 months after loading to monitor gingival profile.
The purpose of the study is to evaluate the use of a magnetodynamic instrument (Magnetic Mallet®, Metaergonomica, Turbigo, Italy) to perform a horizontal bone expansion in edentulous sites that need to be rehabilitated with a dental implant.
the aim of this study is to compare the influence of different palatal vault configurations on the accuracy and scan speed of IO scans in cases of completely edentulous arches. The null hypothesis is that there is no difference in scanning time, and trueness and precision of IO scans between class I, II and III palatal vault configurations.
