The objectives of this prospective clinical research was to evaluate the peri-implant esthetics of immediate single-tooth implants with immediate provisional restoration in the anterior maxilla and the predictability of obtaining primary stability with virtual planning using the Dental Slice© (Bioparts Prototipagem Biomédica, Brasília, Distrito Federal, Brazil) software. Eleven patients, seven men and four women, with a mean age of 50.8 (± 11.8) years and all with gingival phenotype classified as thick, received 14 implants, model Helix Grand Morse™ (Neodent®, Curitiba, Paraná, Brazil), immediately after extraction. The gap between the implant and the dental socket was filled with Extra-Graft® (Silvestre Labs®, Rio de Janeiro, Rio de Janeiro, Brasil), and the provisional was made on a universal abutment with a diameter of 3.3 mm. The positioning, length and diameter of the implants were planned virtually, and the drilling sequence was based on the value obtained in the Hounsfield Unit tool of the software. The esthetic result of soft tissue was evaluated by the Pink Esthetic Score, by two previously calibrated evaluators and prosthetic specialists, in the pre-surgical and post-surgical period of 15 days and 2 months. The weighted Kappa intra-examiner was 0.84 (p <0.000) and the weighted Kappa between examiners was 0.75 (p <0.001). The PES values did not differ between the preoperative period, 15 days and 2 months postoperatively, with a median of 10.5, 11.0 and 12.0 respectively. All implants were subjected to immediate provisionalization and the average installation torque was 37.86 (+ 11.9) Ncm. The predictability between the virtual planning of the implant and its installation was 85.7%, with p <0.009. The installation of immediate implants with immediate provisional restoration in areas of thick gingival phenotype maintained the original characteristics of peri-implant soft tissues, with predictability for obtaining primary stability with this implant model
