Peri-implantitis and its prevention.

Clin Oral Implants Res 2019 Feb 3;30(2):150-155. Epub 2019 Feb 3.

Department of Oral & Maxillofacial Surgery, Red Cross Hospital, Kassel, Germany.

This perspective article on peri-implantitis and its prevention was produced as a supplement to a 3-D, computer-animated film aiming at presenting key characteristics of peri-implant health, the build-up of a biofilm and the ensuing host-response resulting in peri-implant mucositis and, subsequently, peri-implantitis. Treatment concepts for peri-implantitis were briefly reviewed, and prevention of the condition was brought to attention as a priority in implant dentistry. The overview also highlighted the 2017 World Workshop on Classification of Periodontal and Peri-implant diseases and Conditions, in which new disease definitions and case definitions were presented for peri-implant health, peri-implant mucositis, and peri-implantitis.

Titanium dental implants with different collar design and surface modifications: A systematic review on survival rates and marginal bone levels.

Clin Oral Implants Res 2019 Jan 18;30(1):20-48. Epub 2018 Dec 18.

Dentistry Department, Faculty of Medicine of the University of Coimbra, Coimbra, Portugal.

Aim: The aim of this study was to compare clinical and radiographic outcomes of dental implants with different neck characteristics.

Methods: A protocol-oriented search aimed at the question: "In patients subjected to tooth replacement with screw-type dental implants does the modification of the implant neck macro- or microgeometry contribute to the improvement of survival rates and maintenance of the peri-implant marginal bone levels?" Primary outcomes were survival and marginal bone level (MBL) changes evaluated on randomized controlled trials with >10 participants and follow-up >1 year. Risk of bias was evaluated using the Cochrane Collaboration's tool. Read More

Variation in bucco-palatal maxillary sinus width does not permit a meaningful sinus classification.

Clin Oral Implants Res 2018 Dec 6;29(12):1220-1229. Epub 2018 Dec 6.

Division of Oral Surgery, School of Dentistry, Medical University of Vienna, Vienna, Austria.

Objectives: The bucco-palatal sinus width (SW) appears as relevant factor for graft consolidation after maxillary sinus (MS) floor augmentation. The present study aimed to assess (a) SW at different height levels of posterior teeth, (b) possible factors influencing SW, and (c) whether a simple/meaningful sinus classification based on SW is possible.

Methods: The following parameters were recorded on computed tomographies of 76 edentulous and 86 partially edentulous maxillary quadrants displaying 383 tooth sites in total: (a) alveolar ridge height, (b) -area, (c) -width 2 mm apical to the alveolar crest, (d) -width at the sinus floor, and (e) SW and sinus area at a level 2, 4, 6, 8, and 10 mm above the sinus floor.

Sinus floor elevation in sites with a perforated schneiderian membrane: What is the effect of placing a collagen membrane in a rabbit model?

Clin Oral Implants Res 2018 Dec;29(12):1202-1211

Department of Periodontology, School of Dentistry, Kyung Hee University, Seoul, Korea.

Objective: To investigate the healing following sinus grafting in sites with a perforated schneiderian membrane repaired using a collagen membrane, compared to control sites without membrane perforation.

Materials & Methods: Following elevation of the sinus membrane in 16 rabbits, each sinus was assigned to one of the following groups: (a) intentional schneiderian membrane perforation, followed by the placement of a collagen membrane and bone grafting (group SMP) and (b) bone grafting without a perforation of the schneiderian membrane and without a collagen membrane placement (control group). At 2 and 4 weeks (n = 8 for each time-point), microcomputed tomographic (micro-CT) and histomorphometric analyses were performed. Read More
