OBJECTIVES: The aim of this study was to assess the clinical outcomes of a non-surgical treatment protocol for peri-implantitis and to evaluate the influence that some factors could have on the results of this treatment. MATERIAL AND METHODS: In this retrospective case series, patients with at least one implant with peri-implantitis, treated with a non-surgical protocol and with a one-year follow-up, were included. Clinical parameters (probing depth, recession, bleeding and/or suppuration on probing) were collected at baseline, 6 weeks, 3, 6 and 12 months...

OBJECTIVES: To investigate the dimensional changes following the extraction of maxillary second incisors and to evaluate the influence of deproteinised bovine bone mineral on the healing outcomes MATERIALS AND METHODS: The second maxillary incisors in nine dogs were extracted bilaterally in a minimally traumatic manner. Deproteinised bovine bone mineral with collagen (DBBMC) and a collagen matrix (CM) were placed in one socket with the contralateral socket left to heal naturally. After three months of healing, the dogs were sacrificed and the pre-maxilla resected...

OBJECTIVES: To assess the potential trends for the year 2030 in dental implant dentistry in Europe using the Delphi methodology. MATERIAL AND METHODS: A steering committee and a management team of experts in implant dentistry were created and validated a questionnaire including 60 questions, divided in eight topics. The survey was conducted in two rounds using an anonymous questionnaire, which provided the participants in the second round with the results of the first...

OBJECTIVE: Prosthetic abutment height and peri-implant mucosal thickness are considered factors that influence marginal bone remodeling during biological width establishment around dental implants. However, no clinical studies have evaluated their simultaneous effect on marginal bone loss (MBL). This study analyzes the influence of abutment height on MBL around implants surrounded by both thin and thick mucosa up to 12-months after prosthetic loading. MATERIAL AND METHODS: Seventy platform-switched implants with internal hex were placed equicrestally in two groups of patients with different vertical mucosal thickness: thin (≤2...

OBJECTIVES: To compare the removal of simulated biofilm at two different implant-supported restoration designs with various interproximal oral hygiene aids. METHODS: Mandibular models with a missing first molar were fabricated and provided with single implant analogues (centrally or distally placed) and two different crown designs (CCD: conventional and ACD: alternative crown design). Occlusion spray was applied to the crowns to simulate artificial biofilm. Thirty participants (dentists, dental hygienists and laypersons) were equally divided and asked to clean the interproximal areas with five different cleaning devices to further evaluate if there were differences in their cleaning ability...

OBJECTIVES: to evaluated the effect of Cisplatin on bone repair and mineralization around implants and on the mechanical properties of bone tissue. MATERIALS AND METHODS: forty-three Wistar rats were randomly divided into two groups: Cisplatin (CIS, medication) and control (CTL, placebo solution), administered once a week for 4 weeks. After 4 weeks, implants were installed in both tibiae metaphysis. After 30 and 60 days, the animals were sacrificed and their femurs and tibiae removed...

OBJECTIVE: Evaluate in-vitro the changes in the implant surface topography of commercial implants after instrumentation with five decontamination protocols. MATERIAL AND METHODS: Seventy-two titanium implants with a sandblasted and acid-etched (SLA) surface were placed 5mm supra-crestally. Five groups of twelve implants were instrumented with the following protocols: a metal scaler tip (SCAL), a thermoplastic scaler tip (PEEK), a round titanium brush (RBRU), a tufted brush with titanium bristles (TNBRU) and a glycine based air-powder abrasive (GLYC)...

OBJECTIVES: The aim of this RCT was to assess radiographically the effect of abutment height and depth of placement of platform switched implants on interproximal peri-implant bone loss (IPBL) in patients with thin peri-implant mucosa. MATERIAL AND METHODS: 33 patients received one prosthesis supported by 2 implants replacing at least 2 adjacent missing teeth (66 implants). Patients were randomly allocated and implant insertion depth adapted to abutment height groups (3 mm height group the implants were placed 2 mm subcrestally; 1 mm height group, equicrestally)...

OBJECTIVE: To assess the clinical and laboratory time efficiency and quality of outcomes for posterior single implant crowns by means of a model-free digital workflow using digital impressions immediately after implant placement. METHODS: Forty patients missing a single posterior tooth received implant therapy. For within-subject comparison, digital impressions were taken immediately after implant placement and conventional impressions after implant healing. Two monolithic zirconia crowns were fabricated using a laboratory-based CAD-CAM system...

OBJECTIVES: Evaluation of in-vitro efficacy of 3 different implant-surface decontamination methods in a peri-implant bone defect model. MATERIAL AND METHODS: 180 implants were stained with indelible red color and distributed to standardized peri-implant bone defect resin models with a circumferential defect angulation of 30°, 60° or 90° (supraosseous defect). Sixty implants were assigned to each type of defect. All implants were cleaned by the same examiner. For each type of defect 20 implants were cleaned for 2 minutes with one of 3 devices: curette (CUR), sonicscaler (SOSC) or air abrasion with glycine powder (APA)...

The aim of this consensus meeting was to assess the influence of implant neck and abutment characteristics on peri-implant tissue health and stability. Group and plenary discussions were based on two systematic reviews focusing on the effect of titanium implants with different collar designs/ surface modifications and the abutment material on the stability of marginal bone levels (MBL's), peri-implant health, and survival rates. The changes in MBL's were not influenced by the abutment material and were also similar at one- and two-piece implants after one year of loading...
