BIOLOGIC WIDTH AROUND DENTAL IMPLANTS
The biologic width is considered to be essential for maintaining gingival health, especially in the case of teeth in need of restoration. The large use of osseointegrated implants in modern dentistry and the increasing esthetic demands for implant rehabilitations has focused attention on soft tissue reactions to implant placement especially in the area of soft tissue relationship to implant surface. The presence of a quite constant dimension of soft tissue attachment to dental implants, similar for many features to dentogingival junction, has been well documented in histological studies on animal models. Based on similar histological studies, the influence of different variables, like the surgical technique, the surgical protocol, implant loading, implant structure, titanium surfaces and abutment materials on peri-implant biological width has been evaluated. This review demonstrates the present knowledge about this important zone that forms the basis for a successful implant.
Biological Width: The Periodontal Restorative Interlink: Short Discussion
International Journal of Dental and Medical Specialty
Biological width is the natural distance (combine heights) between the base of the healthy gingival sulcus OR epithelial attachment to the tooth and the height of the alveolar bone or connective tissue. For better description of relationship between the periodontal tissues and conservative procedures is to restore form, function, esthetics, and comfort for the dentition. Most of the dentists are aware of biological width, its maintenance and its importance during application of crown lengthening. Relevant publications regarding biologic width, its violation and management were identified up to August 2011 using manual and electronic database search in Medline, Embase, Directory of Open Access Journals, and Google Scholar.
Dentogingival complex: dimension based on biotypes
Puerto Rico health sciences journal, 2013
Estimate the DGC dimensions and determine whether the DGC dimension varies by gingival biotype. A cross-sectional study was performed in the Undergraduate and Prosthodontic Graduate Program clinics of the School of Dental Medicine, University of Puerto Rico from August 2011 to April 2012. A total of 53 participants who needed restorative crowns in their teeth were recruited. Prior to crown preparation, the gingiva was classified as having a thin, mixed or thick biotype, according to transparency, using a standardized 15 UNC Hu-Friedy periodontal probe. The DGC dimension was measured by transulcus probing. Descriptive statistics were calculated in mesial, medial, and distal sites by phenotypes. Differences between and within the sites' DGC dimension mean were determined using a Friedman test. The level of significance was 0.05. Mean DGC dimensions, in millimeters, for all sites measured were: 3.09 (95% CI: 2.91-3.27), 3.40 (95% CI: 3.18-3.62), 2.70 (95% CI: 2.51-2.89), and 3.17 (...

This study examined the naturally occurring dimensions of the denfoglngivai ¡unction In 10 adult human cadaver jaws. The connective tissue attachment, epitheliai attachment, ioss of attachment, and sulcus depth were measured tiistomorphometricaliy for 171 tooth surfaces. iVIean measurements were 1.34 ± 0.84 mm for sutcus depth: hl4 ±0.49 mm for epitheliai attachment: 0.77 ± 0.32 mm for connective tissue atfachment; and 2 92 + 1 69 mm tor lass Of attachment. These dimensions, os measured in this study, support the concept that the connective tissue attachment is a variabie widtf^ within a more narrow distribution and ronge than the epitheiioi attachment, sulcus depth, or toss of attachment.

Biologic width - knowledge key for restorative dentistry
International journal of health sciences
Aim: To elaborate the importance of the concept of biologic width in terms of restorative dentistry. Background: Biological width is the natural distance (combine heights) between the base of the healthy gingival sulcus or epithelial attachment to the tooth and the height of the alveolar bone or connective tissue. For better description of relationship between the periodontal tissues and conservative procedures is to restore form, function, esthetics, and comfort for the dentition. Most of the dentists are aware of biological width, its maintenance and its importance during application of crown lengthening. However, this review will elaborate on its importance in restorative dentistry. This article reviews the anatomy, categories, evaluation, violation, methods to correct the violation of biologic width and its relationship to periodontal health and restorative dentistry. Review Results: Respecting the biologic width and designing restorations accordingly is crucial. Biologic Width ...
Biological Width around One- and Two-Piece Implants Retrieved from Human Jaws
BioMed Research International, 2014
Several histologic studies regarding peri-implant soft tissues and biological width around dental implants have been done in animals. However, these findings in human peri-implant soft tissues are very scarce. Therefore, the aim of this case series was to compare the biological width around unloaded one-and two-piece implants retrieved from human jaws. Eight partially edentulous patients received 2 test implants in the posterior mandible: one-piece (solid implants that comprise implant and abutment in one piece) and two-piece (external hexagon with a healing abutment) implants. After 4 months of healing, the implants and surrounding tissue were removed for histologic analysis. The retrieved implants showed healthy peri-implant bone and exhibited early stages of maturation. Marginal bone loss, gaps, and fibrous tissue were not present around retrieved specimens. The biologic width dimension ranged between 2.55 ± 0.16 and 3.26 ± 0.15 to one-and two-piece implants, respectively ( < 0.05). This difference was influenced by the connective tissue attachment, while sulcus depth and epithelial junction presented the same dimension for both groups ( > 0.05). Within the limits of this study, it could be shown that two-piece implants resulted in the thickening of the connective tissue attachment, resulting in the increase of the biological width, when compared to one-piece implants.

Biologic Width around Dental Implants: An Updated Review
Soft tissue-implant interface is an important anatomical feature contributing to the long-term success of dental implants. Based on the available evidence, different factors may influence biological width around implants including the surgical technique, implant loading, implant surface properties, abutment materials, implant position, and width of the peri-implant mucosa. The purpose of the present review was critical evaluation of the available data, regarding the factors that may influence the biologic width around implants and their subsequent effect on clinical performance of implants. Available literature on this subject published primarily in English from 1921 to 2014, was found by searching several electronic databases and by hand searching relevant journals as well. Totally, 70 relevant articles were selected for this narrative review. The structure of peri-implant mucosa has many similarities, as well as differences with its periodontal counterpart. Most studies report larger values for peri-implant biologic width compared to that of natural teeth. This literature review yielded contradictory data regarding the dimensions of the biologic width when different influential factors were taken into account.
