Employment of U‐Shape Technique at Reentry Surgery for Papillae Coronal Migration on the Rehabilitation of Anterior Single Implant: 3‐Year Follow‐Up Case Report

Abstract

Introduction The rehabilitation of a maxillary single dental implant represents a great challenge at clinical practice. Harmony among the implant‐supported crown and adjacent teeth is required in which concerns pink and white esthetics. The aim of the present case report is to depict a multidisciplinary treatment in which the U‐shape flap technique for papillae preservation at second stage surgery was used. Case Presentation One female patient presenting an un‐rehabilitated dental implant at the left central incisor position sought treatment at the Centre of Education and Research on Dental Implants (CEPID). Alterations of color, shape, and position were observed on the anterior maxillary teeth. For proper treatment planning, radiograph, wax‐up, and mock‐up were performed. Second stage surgery was performed by the U‐shape flap technique. A trunnion abutment was installed at the implant and a provisional subcontoured cemented crown was manufactured. Dental bleaching, feldspathic veneers, and a ceramic crown were performed. Oral hygiene instructions were recommended. Follow‐up appointments were set at 1.5 and 3 years after restoration placement. After 3‐year follow‐up, soft tissue stability and health were preserved and papillae coronal migration around the single dental implant was observed. A complication‐free treatment was reached, and patient demonstrated satisfaction towards esthetic and function. Conclusions The use of U‐shape technique at second stage surgery associated to adequate prosthetic contour improved soft tissue esthetic outcomes, while the multidisciplinary treatment planning provided adequate solutions, refining harmony between dental and implant‐supported components.

Comparison between Rolled and Nonrolled U-Shaped Flap in the Second Stage of Dental Implant Surgery: A Randomized Clinical Trial

“…Different methods and approaches were tried to get better esthetic and functional soft tissue results around dental implants in the esthetic zone [9][10][11].…”

Subsequently, rolling off and fixation of the de-epithelized part of the flap labially with two stitches of 4/0 black silk suture on the mesial and distal sides of the flap [9,12,13] (Figure 1). e temporary crown was fabricated by using the dental implant abutment with packable and flowable composite.…”

“…Different types of flap designs (U-shaped flap, apically repositioned partial thickness flap, rotated double-pedicle flap, and modified roll flap) are utilized in the second stage of dental implant surgery; each method claims to be superior to the other methods [9][10][11].…”
