Accurate Transfer of Peri‐implant Soft Tissue Emergence Profile from the Provisional Crown to the Final Prosthesis Using an Emergence Profile Cast

Abstract

This article describes a technique that results in an implant restoration that mimics accurately in its emergence profile that of the carefully crafted and customized provisional restoration. The reproduction of the soft tissue contour from the provisional to the final restoration results in an improved esthetic outcome of the final restoration.

“…Asimismo, cumplen una importante función en la maduración y conformación de los tejidos blandos que rodean al implante, ya sea intentando conservar de la mejor forma posible la anatomía gingival de una pieza que se acaba de extraer, como modificando la forma plana de la mucosa de un reborde desdentado, buscando imitar la forma festoneada natural de las encías que rodean las piezas naturales. Luego, es posible transferir al laboratorio la forma obtenida en los tejidos blandos durante la etapa con provisorios, en la toma de impresión definitiva (22) utilizando cofias de transferencia personalizadas (Figs. 6, 8).…”

“…They also play an important part in the maturation and shaping of the soft tissues which surround the implant, both by attempting to maintain in the best way possible the gingival anatomy of a tooth which was just removed, and altering the flat shape of the mucosa of an edentulous ridge, trying to replicate the naturally scalloped shape of the gums surrounding natural teeth. Afterwards, it is possible to transfer to the laboratory the shape obtained in the soft tissues during the phase with provisional restorations, when the final impression the dental technician (22) is taken using personalized transfer copings (Figs. 6, 8).…”

Soft tissue manipulation for single implant restorations

“…This soft tissue maturation process may take up to two months depending on the degree of manipulation required. 19 Where there is a need for implant restoration removal the soft tissues can collapse due to loss of support. This can be overcome by placing an appropriately contoured healing abutment or customised index while the restoration is out of the mouth (Figs 10-11).…”

Accurate transposition of peri-implant soft tissue morphology in anterior prosthesis: case report

“…Restorations with appropriate contour have a significant effect on oral hygiene, health and esthetics of peri-implant tissues. 6,7 With a view to obtaining the ideal emergence profile for the permanent prosthesis, implant treatment must be conducted, as from the beginning, with techniques and material that allow so, with adequate implants ideally placed in tridimensional position, so as to provide favorable gingival contour, 1,8,9 followed by the correct choice of healer 9,10 and use of provisional restoration.…”

“…Most impression copings are of cylindrical shape and do not resemble the shape of natural teeth. 10 Thus, using them for final impression procedures will result in casts that do not reproduce the features of soft tissues; as a result, the laboratory technician will have difficulty manufacturing the emergence profile, 6 which might hinder permanent restoration success. 22 A number of techniques for transposition of the emergence profile from a provisional restoration to a permanent one have been reported, as it is the case of the method in which two identical provisional restorations are manufactured and one of them is used for impression taking.…”
