ABSTRACT
Clinical crown lengthening procedure would be an effective method for overcoming adverse clinical condition such as short abutment length. There are three kinds of methods in clinical crown lengthening, those are, surgical crown lengthening, orthodontic extrusion and surgical extrusion. Clinicians have to try their best to choose a proper method among those for favorable results. This report aims to review the considerations in each method with various cases and to suggest a decision flow for appropriate selection.

Este estudo propôs verificar a eficácia da utilização do laser de baixa intensidade (LBI) como terapêutica alternativa à terapia medicamentosa na redução da dor pós-operatória de cirurgias para aumento da coroa clínica. A amostra foi constituída por 30 pacientes adultos que foram divididos aleatoriamente em dois grupos: Grupo controle (n = 14) tratado com prescrição medicamentosa (Paracetamol 750 mg) e Grupo experimental (n = 16) tratados com laserterapia de baixa intensidade (seis aplicações pontuais, sendo três na região vestibular e três na palatina/lingual, de 20 mW/10 segundos, com comprimento de onda 660 nm, de 5 joules/ponto) imediatamente após o ato cirúrgico, em sete dias e 14 dias. Pode-se observar que o grupo experimental obteve melhores resultados, ou seja, menos dor que o grupo controle, porém sem diferença estatisticamente significante. Concluímos que o protocolo de aplicação LBI não apresentou resultados estatisticamente significantes, porém, a LBI foi uma terapia alternativa eficaz na redução da dor pós-operatória.
This study aimed to verify the effectiveness of the use of low intensity laser therapy (LILT) as an alternative therapy to drug therapy in reducing the postoperative pain of surgeries to increase clinical crown. The sample consisted of 30 adult patients and were randomly divided into two groups: control group (n=14) treated with conventional medication prescrition (Paracetamol 750mg) and experimental group (n=16) treated with low intesensity laser therapy (six specific applications, three in the buccal region and three in the palatal/lingual mW/10 20 seconds with a wavelength of 660 nm, 5 joules/ point) immediately after surgery, 7 and 14 days. In this study, we can observe that the experimental group achieved better results but the LILT was less pain referred to the control group, but no statistically significant difference. We conclude that the LILT application protocol did not result in statistically significant results. But based on the results obtained, we can conclude that LILT was an effective alternative therapy in reducing referred pain postoperatively.

When a tooth adjacent to implant has coronal damages caused by severe dental caries or fracture, the clinical crown lengthening by forced eruption makes it possible to get esthetic restoration due to the prevention of alveolar crestal bone resorption and loss of interdental papilla. A 54-years-old male patient wanted prosthetic treatment because his anterior 3 unit bridges had fallen out. A right maxillary central incisor showed mild dental caries but a right maxillary canine lost most clinical crowns. Forced eruption combined with a gingival fiberotomy of a right maxillary canine was performed for 1 month after the dental implant had been simultaneously placed with bone grafts on a right maxillary lateral incisor. About 5 months after implant placement, 2nd surgical operation was performed. The provisional restorations were adjusted to make esthetic gingival contour for 8 weeks. The porcelain fused gold restorations were fabricated and set. The patient was satisfied with the final restorations in esthetic and functional aspect.
