Osseous Surgery for Crown Lengthening: A 6‐Month Clinical Study

Abstract

These data suggest that there is a significant tissue rebound following crown-lengthening surgery that has not fully stabilized by 6 months. The amount of tissue rebound seems related to the position of the flap relative to the alveolar crest at suturing. These findings support the premise that clinicians should establish proper crown height during surgery without overreliance on flap placement at the osseous crest.

Erbium Laser-assisted Closed-flap Crown Lengthening: A Review of the Literature

“…2,15,23,24 Dyer recommends a sweeping motion from the mesial to the distal. 8 Flax uses a "sewing machine stitch" motion (precise up and down movements) for his clinical cases. 15 However, there are no controlled longitudinal or cohort studies supporting use of lasers for clinical crown lengthening using the closed-flap technique.…”

“…A traditional crown-lengthening procedure involves an open-flap surgery and removal of bone with rotary instruments. 1,2,7,8 The healing period for such a procedure is usually 4 to 6 weeks. 1,7,8 It may lead to postsurgical complications, such as excessive bleeding, infection, repositioning of the marginal gingiva, and inflammation.…”

“…1,2,7,8 The healing period for such a procedure is usually 4 to 6 weeks. 1,7,8 It may lead to postsurgical complications, such as excessive bleeding, infection, repositioning of the marginal gingiva, and inflammation. 7,9,10 Erbium lasers offer an alternative which is minimally invasive and eliminate most of the complications faced in a conventional procedure.…”

Avaliação longitudinal, clínica e radiográfica, do processo de reparo dos tecidos periodontais marginais após cirurgia ressectiva de aumento de coroa

“…), efetuando a troca semanal da solução reveladora e fixadora. Como o término cervical foi mantido no mesmo nível em todas as radiografias, uma análise comparativa entre medidas lineares obtidas na imagem pós-osteotomia (medida inicial), pré-osteotomia e de controle pós-operatório (Tabela 4.1) possibilitou detectar alterações no nível ósseo M e D. 18,35 . Adicionalmente, todos os pacientes receberam orientação quanto aos demais cuidados pós-operatórios, uso cuidadoso do fio dental e escovação delicada sobre a área operada durante a primeira semana pós-operatória.…”

“…Adicionalmente, todos os pacientes receberam orientação quanto aos demais cuidados pós-operatórios, uso cuidadoso do fio dental e escovação delicada sobre a área operada durante a primeira semana pós-operatória. As suturas foram removidas após um período que variou de sete a dez dias da cirurgia 18 .…”
