The aim of this study was to compare the success rates after 1 and 2 years conventionally early loaded pairs unsplinted ITI implants supporting mandibular overdentures in edentulous patients. Twenty-four participants (age range 55-80 years) were randomly allocated with maximum concealment two treatment groups. In first group, allowed heal for 12 weeks before being functionally (control) second group had 6 healing identical loading. All new conventional complete maxillary dentures prior...
ABSTRACT Background : Step‐wise reduction in loading protocols is necessary to evaluate early of implants with mandibular overdentures. Purpose To compare the success rates two different dental implant systems following conventional or patients being rehabilitated Materials and Methods Forty‐eight edentulous participants were randomly allocated systems: one a machined titanium surface (Sterioss, Nobel Biocare, Yorba Linda, California, USA) other roughened (Southern Implants, Irene, South...
To compare the levels of patient satisfaction with either conventional mandibular bilateral distal extension partial dentures or those assisted by implants.Forty-eight participants who were dissatisfied their existing opposing complete maxillary selected for a multicentre prospective study in New Zealand, Colombia and Netherlands. A control group 12 Zealand received dentures. Three test groups involving 36 (12), (12) Netherlands implants second molar regions. After loading, initially had...
To investigate the presence of titanium particles in peri-implant tissues cases diagnosed with peri-implantitis, and to identify immunological reactions that these may elicit. Ten tissue biopsies patients clinically radiographically peri-implantitis were obtained from archives Oral Pathology Centre, University Otago. The inclusion criteria involves: bleeding on probing, ≥6 mm probing depth ≥3 radiographic bone loss around dental implant. Peri-implant samples evaluated using scanning electron...
The aim of this randomised controlled trial was to assess clinical, radiographic and patient reported outcomes narrow versus standard diameter titanium zirconium (TiZr) implants supporting single crown restorations in posterior sites with limited bone width. Participants requiring replacement missing teeth implant-supported crowns were randomly allocated into 2 treatment groups: (3.3 mm) or (4.1 implant. All restored screw-retained monolithic zirconia crowns. changes marginal level (MBL)...
Evaluation of patient satisfaction is critical to assessing the quality care. In New Zealand, there are limited studies evaluating patients receiving treatment by dental students. The aim this study was evaluate current levels and factors that influence with non-surgical periodontal provided fourth-year students at University Otago Faculty Dentistry, along areas requiring improvement. This utilised a mixed-methods approach. A 29-item electronic survey completed 41 eligible participants....
Abstract Background Further validation of the risk indicators / predictors for peri‐implant diseases is required to allow clinicians and patients make informed decisions optimize dental implant treatment outcomes. The aim this study was build prediction models, using Chi‐square automatic interaction detection (CHAID) analysis, determine which systemic‐, patient‐, implant‐, site‐, surgical‐ prostheses‐related had more impact on onset diseases. Methods A retrospective analysis 200 who received...
Prospective evaluation of the early loading unsplinted Brånemark implants with mandibular overdentures opposing conventional dentures is not evident in implant-related literature.To clinically evaluate progressive and 20 conical edentulous mandibles overdentures.Ten patients all had two placed anterior mandible mandatory primary stability bicortical anchorage. Ball abutment connection was performed simultaneously. Previously constructed were temporarily relined tissue conditioner...
ABSTRACT Background : Evidence‐based reports are needed to support the application of a one‐stage surgical protocol for unsplinted implants supporting mandibular overdentures. Purpose To examine feasibility and success using two different dental implant systems (originally designed two‐stage operative technique) procedure in patients being rehabilitated with Materials Methods The study sample involved 24 edentulous subjects (aged 55–80 yr) randomly allocated systems, one machined titanium...
Abstract Objective To determine implant survival and prosthodontic maintenance of implant‐assisted mandibular removable partial dentures in a multicentre prospective study up to 10 years. Materials methods Forty‐eight participants with distal extension were selected. A control group 12 New Zealand had new conventional made. Three test groups 36 ( n = 12), the Netherlands 12) Colombia bilateral implants placed. Surgical outcomes documented only healing caps placed (Stage 1) an attachment...
ABSTRACT Background: Maxillary implant overdentures opposing mandibular two‐implant are an underused treatment option for edentulous patients. Fewer implants, simple surgery, and short healing periods may increase patients' acceptance of this concept. Purpose: To determine success, after overdenture loading, three narrow‐diameter roughened‐surface implants placed in maxillas, using a one‐stage surgical procedure, 12‐week period, overdentures. Materials Methods: Forty participants with were...
ABSTRACT Background : Before early functional loading of unsplinted implants with mandibular overdentures can become widespread, more clinical studies are needed to investigate the success approach. Purpose To evaluate rates two types roughened titanium surface 2‐week paired interforaminal overdentures. Materials and Methods Random allocation divided 24 strictly selected edentulous participants into groups, each group receive a different implant system (ITI Dental Implant System, Straumann...
The aim of this study was to compare the clinical effectiveness a powered toothbrush (Braun Oral-B Plaque Remover 3-D) and manual soft (Oral-B Squish-grip brush) for control supragingival plaque tissue inflammation around implants supporting mandibular overdentures.The sample involved 40 edentulous subjects, aged 55-80 years, having 2 unsplinted complete removable overdenture opposed by maxillary denture. In single-blinded, randomised, cross-over trial, two 6-week experimental phases were...
