Study Overview
Brief Summary
Maintaining the general health and well-being of patients is the main goal of dental therapy. However, tooth extraction is indicated when teeth cannot be maintained in a status compatible with health, adequate esthetics, function, and/or for strategic reasons. A variable degree of alveolar ridge atrophy related to bone resorption is initiated immediately after removal of a tooth due to the local physiologic remodeling and the inflammatory response. Ridge resorption is more accentuated in the horizontal dimension, followed by the vertical mid-facial and vertical mid-lingual in non-molar and molar teeth. Among local periodontal phenotypic characteristics, facial bone thickness at the time of tooth extraction seems to be strongly associated with the extent of alveolar bone resorption.
Dental implants have increased in popularity due to their unique ability to replace teeth. During the planning phase of implant therapy, one of the main parameters assessed is the amount of residual alveolar ridge. Therefore, when tooth replacement therapy via dental implant is considered, adequate management of the site is critical to predictably preserve or reconstruct the architecture of the alveolar ridge, particularly in the anterior aesthetic zone, where its structure play a crucial role in the maintenance of function, health and esthetics. Generally, with appropriate treatment planning and execution, the adequate primary mechanical stability of the dental implant is achieved. However, bone and/or soft tissue augmentation procedures could be needed for the adequate management of deficient edentulous ridges at the time of implant placement, and these types of treatments could considerably increase the risk of morbidity, treatment expenses, and length of treatment time. Nevertheless, Implant placement with additional bone contour augmentation therapies have shown their effectiveness in the short-, mid- and long-term in contemporary dental practice.
However, to the present date, there is no information available in the literature regarding patient-reported outcome measures in patients that received tooth replacement therapy via dental implants with additional contour bone augmentation in the short-, mid- and long-term.
Detailed Description
This study is designed as a serial cross-sectional study. Subjects who had undergone an implant placement procedure involving bone contour augmentation procedure via GBR in the anterior aesthetic zone at the University of Bern School of Dental Medicine, Switzerland will be screened and invited for a survey. During the recall exams, patient-reported outcomes will be obtained utilizing standardized questionnaires. These outcome measures will enable us to compile short-, mid-, and long-term data about the patient-reported outcomes measures of tooth replacement therapy with dental implants and additional bone contour augmentation procedure and establish possible correlation with patient (i.e., age, sex, systemic diseases) and surgical-related factors (i.e., location and extension of the procedure, needed for vertical releasing incisions, previous management of the extraction site, etc).
The findings of this study could bring a valuable perspective on the replacement of missing teeth with dental implants and contour augmentation procedures and would provide clinicians and researchers novel knowledge to guide the clinical decision-making process.
Project population, inclusion and exclusion criteria Subjects who had undergone implant placement procedure involving bone contour augmentation procedure via Guided Bone Regeneration in the anterior esthetic zone at the University of Bern School of Dental Medicine, Switzerland will be screened and invited for a survey. The inclusion criteria are: 1) previous information on the bone augmentation procedure; 2) patients willing to provide an informed consent and attend the study, and 3) absence of any further surgical procedure involving the area of interest. The exclusion criteria are: 1) patients that would not remember where the surgical procedure was performed; 2) unwilling or unable to sign the informed consent. Besides them, and taking into consideration that no further interventions are provided in this study, no further exclusion criteria are defined.
Patients who expressed an interest to participate in this study at the clinical screening examination, would be informed of the purpose and timeline of the study. All potential subjects will be required to read, understand, and sign the consent form, which included a thorough explanation of the study design, as well as expected benefits and possible risks of participating in the study.
The initial recruitment of patients would be based on their confirmation of recalling the implant placement surgery involving the bone contour augmentation procedure via GBR, its purpose, and the area of the oral cavity where the procedure was performed. In the short-term group the patients would be followed at 1-week, 2-weeks, one and three months after surgery. Mid-term would-be patients that had the procedure performed between one up to 5 years. Long-term group would be patients that had the procedure performed from 5 years up to 20 years.
