Article
Objectives: To assess the long-term outcomes (>4 years) following combined surgical resective/regenerative therapy of advanced peri-implantitis lesions using two surface decontamination methods. Material & methods: Fifteen patients (n = 15 combined supra- and intrabony defects) completed a follow-up observation period of 7 years. The treatment p...
Article
To assess the prevalence of peri-implant health or disease for a two-piece implant system with a tube-in-tube internal connection on the short-, medium- and long term. For this cross-sectional analysis, 238 patients with a total of n = 512 implants were screened in six private practices and one university clinic in Germany. Peri-implant health and...
Article
This case report presents a 3-year follow-up of the clinical outcomes of a combined surgical therapy for advanced peri-implantitis with concomitant soft tissue volume augmentation using a collagen matrix. One patient suffering from advanced peri-implantitis and a thin mucosal biotype underwent access flap surgery, implantoplasty at buccally and sup...
Article
To investigate the impact of two surface decontamination methods on the long-term outcomes following combined surgical resective/regenerative therapy of advanced peri-implantitis lesions. Seventeen patients (n = 17 combined supra- and intrabony-defects) completed the 48 months follow-up observation following access flap surgery, granulation tissue...
Article
To investigate the impact of a cross-linked- (VN) collagen membrane on the long-term stability of peri-implant health over 6 years. Vestibular dehiscence-type defects at titanium implants (19 patients, 19 implants) were augmented using a natural bone mineral and randomly allocated to either VN or a native collagen membrane (CM) and left to heal in...
Article
Objectives: Mucosal recessions are a common finding following surgical treatment of peri-implantitis, thus compromising the overall esthetic outcome of implant therapy. This case series aimed at evaluating the clinical outcome of a combined surgical therapy of advanced peri-implantitis lesions with concomitant soft tissue volume augmentation. Mat...
Article
The study aimed at evaluating the 2-year results obtained following combined surgical resective and regenerative treatment of advanced peri-implantitis defects comparing two methods of surface debridement/decontamination (DD). Twenty-four patients (n = 26 combined supra- and intrabony defects) completed the 24 months follow-up observation following...
Article
To evaluate radiological bone level (RBL) (i.e. cone-beam computed tomography) and histological bone levels (HBL) as well as re-osseointegration [bone-to-implant contact (BIC)] after surgical resective (i.e. implantoplasty) and/or regenerative therapy of advanced ligature-induced peri-implantitis in dogs. At all defect sites (n=6 dogs, n=48 implant...
Article
In recent years dental implants have developed into an established method for replacing missing teeth. The implants serve as anchoring elements for permanent as well as removable teeth and have revolutionized the options for prosthetic healthcare. However, the increasing number of dental implants and the more commonly present general medical risk f...
Article
The aim of this prospective, parallel group designed, randomized controlled clinical study was to evaluate the effectiveness of an air-abrasive device (AAD) for non-surgical treatment of peri-implantitis. Thirty patients, each of whom displayed at least one implant with initial to moderate peri-implantitis, were enrolled in an oral hygiene program...
Article
To investigate the impact of residual defect height (RDH) following guided bone regeneration (GBR) in dehiscence-type defects on the long-term stability of peri-implant health after a period of 4 years. The RDH values in dehiscence-type defects at titanium implants were clinically assessed after 4 months of submerged healing following augmentation...
Article
Concerning pen-implant infections, a general differentiation is done between mucositis which is limited to the pen-implant soft tissue and peri-implantatis, which also affects the surrounding bone. To avoid pen-implant infections, a subsequent analysis and prevention of risk factors is a special need. From the actual literature it can be concluded...
Article
Durch die zunehmende Zahl zahnärztlich inserierter Implantate nehmen insgesamt auch die Komplikationen durch periimplantäre Entzündungen mehr und mehr zu. Um betroffene Implantate adäquat behandeln und möglichst auch erhalten zu können, kommt nicht nur der Kenntnis über mögliche Therapieverfahren, sondern auch dem Wissen über die Ursächlichkeiten u...
Article
The study aimed at investigating the impact of two surface debridement/decontamination (DD) methods on the clinical outcomes of combined surgical treatment of peri-implantitis. Thirty-two patients suffering from advanced peri-implantitis (n=38 combined supra- and intra-bony defects) were treated with flap surgery, granulation tissue removal, and im...
Conference Paper
Objectives: The aim of this prospective, parallel group designed, controlled clinical study is to evaluate the effectiveness of an air-powder system for the treatment of peri-implantitis. Methods: Fourteen patients, each of whom displayed at least one implant with initial or moderate peri-implantitis, were randomly instrumented using either (1) an...
Article
The present study aimed at investigating the impact of defect configuration on the clinical outcome of surgical regenerative therapy of peri-implantitis lesions using a natural bone mineral in combination with a collagen membrane (NBM+CM). Twenty-seven patients (n=27 defects) exhibited three different types of peri-implantitis lesions including eit...
Article
The present case series aimed at investigating the 4-year clinical outcomes following surgical regenerative therapy of peri-implantitis lesions using either a nanocrystalline hydroxyapatite (NHA) or a natural bone mineral in combination with a collagen membrane (NBM+CM). Twenty patients suffering from moderate peri-implantitis (n=20 intrabony defec...
Article
To investigate the influence of platform switching on crestal bone level changes at non-submerged titanium implants over a period of 6 months. Titanium implants (n=72) were placed at 0.4 mm above the alveolar crest in the lower jaws of 12 dogs and randomly assigned to either matching or non-matching (circumferential horizontal mismatch of 0.3 mm) h...
