Effect of Digitally Customized Healing Abutment on Emergence Profile of Single Implant Restoration: A Prospective Clinical Trial

past the free margin of the gingiva into the oral environment.3 Buccolingually and apicoocclusally, the emergence profile extends from the base of the gingival sulcus at the cementoenamel junction (CEJ) to the contact area.The interproximal contact areas are IntroductIonThe long-term success of a prosthetic reconstruction with implants has been well documented.The success of a single maxillary anterior implant crown also depends on several factors, namely, treatment planning, quantity and quality of bone, surgical technique, type of restoration and oral hygiene, esthetics, and follow-up.The survival of implants is also related to the transmucosal tissue and its stability around the implant collar. 1 An implant restoration needs to be in harmony with the crown form of the adjacent natural teeth as well as with the contralateral natural tooth. 1 For a favorable prognosis, an artificial crown form must approximate natural tooth morphology, and deviation from natural tooth form may stress the dental tissue beyond the capacity to resist disease.The primary etiological factor for peri-implant disease is plaque accumulation.Plaque retention is commonly seen on and around irregular over-or under-contoured restorations.Therefore, creating an ideal cervical contour of an artificial restoration that does not harbor plaque is required for long-term prognosis.2 Croll defines the emergence profile of a tooth as that portion of axial tooth contour that extends from the base of the gingival sulcus 1,4,
