Previous issue date: 2016-08-18 / OBJETIVO: O objetivo deste estudo foi determinar, atrav?s de diferentes m?todos, o bi?tipo periodontal de dentes e espa?os prot?ticos em pacientes pr?vios ? reabilita??o unit?ria com implantes osseointegrados e carga imediata em ?reas est?ticas. METODOLOGIA: trata-se de um estudo de diagn?stico, por meio da avalia??o periodontal dos pacientes previamente ao tratamento com pr?teses unit?rias sobre implantes osseointegrados. Uma amostra inicial de 34 pacientes foi considerada. Foram inclu?dos no estudo pacientes com aus?ncias unit?rias em ?rea est?tica e sa?de periodontal. Foram exclu?dos os pacientes com m?ltiplas aus?ncias candidatos a reabilita??o com pr?tese unit?ria em regi?o n?o est?tica. RESULTADOS: Foram encontradas correla??es estatisticamente significativas entre espessura horizontal da mucosa no espa?o prot?tico e espessura vertical da mucosa no espa?o prot?tico (p<0,001) e espessura horizontal da mucosa nos dentes adjacentes ao espa?o prot?tico e espessura horizontal no espa?o prot?tico (p=0,001). N?o foram encontradas correla??es entre as espessuras horizontal/vertical e as demais vari?veis de interesse: transpar?ncia ? sondagem, g?nero, altura e largura das coroas e papilas, profundidade de sondagem vestibular e raz?o altura/largura de coroas e papilas. A an?lise de conglomerados (clusters) resultou em dois grupos bem definidos, G1 (bi?tipo espesso) e G2 (bi?tipo fino) que, quando analisados em rela??o as vari?veis acima, apresentou diferen?as significativas para transpar?ncia a sondagem (p=0,04), espessura vertical do espa?o prot?tico (p<0,001), espessura horizontal dos dentes adjacentes (p<0,001), profundidade de sondagem vestibular (p=0,05) e raz?o altura/largura das papilas dos dentes adjacentes (p=0,02). O teste de transpar?ncia ? sondagem obteve 77,8% de sensibilidade e 56,3% de especificidade, com acur?cia geral de 67,7%. CONCLUS?O: Os bi?tipos periodontais s?o classific?veis, apresentam distintos par?metros morfom?tricos e t?m como principais influenciadores espessura gengival horizontal, espessura gengival vertical e transpar?ncia ? sondagem vestibular para classifica??o. O m?todo da transpar?ncia ? sondagem foi eficaz no diagn?stico dos tipos de bi?tipos periodontais avaliados. / The aim of this study was to determine, by analyzing different methods of
determination, the periodontal biotype of teeth and prosthetic spaces in patients prior
to the unitary rehabilitation with dental implants, including anterior and posterior
regions. and immediate loading in aesthetic areas. This is a diagnostic study through
evaluation of periodontal patients before treatment unit prosthetic dental implants. An
initial sample of 34 patients was considered. The study included patients with unit
absences in cosmetic area and periodontal health. They excluded patients with
multiple absences candidates for rehabilitation with unitary prosthesis in no aesthetic
region not exposed to smile. The probing depth, transparency on probing, the presence
of recession, the sizes of crowns and buds adjacent to the prosthetic space, the
horizontal gingival thickness and the horizontal and vertical thickness of keratinized
tissue were evaluated parameters. Significant correlations were found between
horizontal mucosa thickness for the prosthetic vertical space and mucosal thickness
of the prosthetic area (p <0.001) and the horizontal thickness of the mucosa adjacent
to the prosthetic teeth horizontal space and thick space for the prosthetic (p = 0.001).
There were no correlations between the horizontal / vertical thickness and other
variables of interest: the transparency survey, gender, height and width of the crowns
and buds, depth vestibular probing and right height / width of crowns and buds. The
cluster analysis (clusters) cluster resulted in two well defined groups, G1 (thick biotype)
and G2 (thin biotype) which, when analyzed for the above variables, showed significant
differences for transparency survey (p = 0.04) vertical thickness of the prosthetic area
(p <0.001), horizontal thickness of the adjacent teeth (p <0.001), buccal probing depth
(p = 0.05) and ratio height / width of the papillae of adjacent teeth (p = 0.02 ). The poll
transparency test achieved 77.8% sensitivity and 56.3% specificity with overall
accuracy of 67.7%. Periodontal biotypes are classifiable, have different morphometric
parameters and have as key influencers horizontal gingival thickness, vertical gingival
thickness and transparency vestibular probing for classification. The method of
transparency on probing was effective in diagnosing types evaluated periodontal
biotypes.
