Treatment concepts for the management of Peri-Implant disease

Abstract: The management of infectious diseases affecting osseointegrated implants in function has become a demanding issue in implant dentistry. While nonsurgical therapy was effective in the treatment of mucositis lesions, for peri-implantitis, mechanical debridement alone has shown limited efficacy. Adjunctive measures (e.g. local antibiotics/ antiseptics, laser application) may be effective in arresting disease progression at initial sites, however, moderate to advanced peri-implantitis lesions commonly require a surgical intervention. Previous studies have indicated that surgical treatment of peri-implantitis with concomitant placement of a bone filler is associated with clinical and radiographic improvements on both short- and long-term periods. However, the available evidence also suggests, that the effectiveness of regenerative treatment approaches is influenced by several factors, such as the type and configuration of the defect, implant surface characteristics, as well as the method of surface decontamination.

Autogenous tooth roots for localized alveolar ridge augmentation

Abstract: Preclinical and clinical data provide evidence, that tooth roots reveal a structural and biological potential to serve as alternative autografts for localized ridge augmentation. In fact, dentin reveals a similar anorganic and organic composition as bone, features osteoconductive as well as osteoinductive properties and also gets involved in the bone remodeling process.

This presentation will elucidate this new biological concept and focus on associated surgical procedures for current and future applications.

CBCT

For several years, 2D (i.e. periapical and panoramic images) have been the state-of-the-art imaging method assisting on the diagnosis and treatment planning in Implantology. As these are two-dimensional images, some areas might not be possible to evaluate clearly, due to overlapping of anatomical structures and geometric distortion. In the present, imaging guidelines focusing into the use CBCT imaging to overcome these problems are relevant to discuss. Implementing CBCT may benefit the field of Implantology as an additional diagnostic method to be used in complex cases, and in those cases in which traditional two-dimensional imaging techniques do not give clear answer. However, the clinical documentation of the diagnostic accuracy of CBCT within Implantology is yet to be disclosed – especially now, when guided implant rehabilitation is a reality. Further, the society gain from implementing CBCT in the decision-making and therapeutic process in relation to diagnosis and treatment planning is far from be defined. In other words, we need to clarify how the use of CBCT will affect treatment choice and (eventually) its outcome. In this lecture, we will discuss the state-of-art of using CBCT within Implantology, as well as the technical aspects of CBCT with could interfere with its proper use in the clinic

Immediate implant replacement – unpredictable or unbelievable

Immediate implant replacement – unpredictable or unbelievable

Immediate implant placement and provisionalization (IIPP) is often associated with mid-facial recession and unpredictable esthetic outcomes. Although similar success rates on the field of osseointegration are achieved both with early and delayed placement protocols, there was a lack of clinical evidence concerning long term esthetic outcomes. Also a firm description of an IIPP protocol was lacking. Based on the current literature Edith Groenendijk described an IIPP protocol and has beed working with it since 2009. A retrospective study was published in 2017 and showed promising results. In cooperation with two universities and 4 private clinics, a clinical prospective multicenter study on the long term stability of the buccal hard tissue and esthetic outcome was started in 2014. This protocol results in minimal discomfort and excellent and predictable esthetic outcomes. In comparison with the conventional method the treatment period is diminished from 18-24 months to 4-6 months, takes only 1 flapless surgery in comparison with 2 to 5 more invasive surgeries using the conventional methods. Instead of wearing a loose flipper a temporary fixed crown is made for the healing period.

Genopbygning af kæbeknoglen – what not to like.

Manglende eller mistede tænder erstattes i stigende grad med implantater. Imidlertid kan implantatbehandling være en behandlingsmæssig udfordring på grund af manglende kæbeknogle. Genopbygning af processus alveolaris er derfor ofte nødvendig enten før eller i forbindelse med implantatindsættelse, men hvilken behandlingsmodalitet og transplantationsmateriale giver det mest forudsigelige og holdbare behandlingsresultat med mindst risiko for komplikationer.

I foredraget præsenteres fordele og ulemper ved de forskellige typer af transplantationsmaterialer og kirurgiske genopbygningsteknikker med fokus på horisontal og vertikal genopbygning af kæbeknoglen med anvendelse af autologt knogletransplantat og knogleerstatningsmaterialer inkl. lateral genopbygning af processus alveolaris, sausage teknik, split-crest teknik og sandwich teknik. Endvidere præsenteres evidensbaseret behandlingsretningslinjer til protetisk rehabilitering af den bagerste del af overkæben med sinusløftprocedure eller korte implantater.

Strength and fracture toughness of zirconia dental ceramics used in implant dentistry.

Strength and fracture toughness of zirconia dental ceramics used in implant dentistry. How reliable is zirconia as abutment, prosthetic framework, crown and implant material” based on in vitro and in vivo studies

Yttria stabilized zirconia ceramic is a perfect biocompatible material used in restorative dentistry over 15 years. Its success is mainly due to the discovery of its phase transformation toughening effect when stressed. Its high strength and high toughness among the ceramics has opened the door to a multitude of clinical restorative applications from full contour ceramic framework to abutments and implants. Newer more translucent zirconias are on the market. It is therefore critical to understand this material in terms of processing, grinding, machining and sandblasting surface treatments, strength, toughness, reliability and fatigue behavior. Zirconia remains a brittle material and fractures are part of clinical experiences made for veneered zirconia crowns and bridges, zirconia framework, abutments and implants. This presentation will provide a thorough understanding of the material science but also illustrate clinical and processing errors based on failure analyses regarding zirconia restorations used in implantology and prosthetic dentistry.
