Immediate Loading of Implants in the Aesthetic Zone Using Three-dimensionally Printed Provisional Crowns: a 1-year Prospective Case Series Study

Starting soon

Conditions studied: Dental Implants, Single-tooth, Crown

In brief

• Background There is a growing tendency to place a provisional crown immediately following implant placement. Clinical advantages are shortening of treatment duration and soft tissue guiding during healing resulting in better aesthetic outcomes. It was shown that good esthetic results can be achieved on the long term with immediate provisionalization of single-tooth implants placed in either fresh extraction sockets or after alveolar ridge preservation/reconstruction in the maxillary esthetic zone. One recent development in three-dimensional printing is digital press stereolithography (DPS), which overcomes the challenges of printing highly-filled viscous materials. This enables the use of more durable materials than traditional three-dimensionally printed provisional crowns and allows for rapid additive production of prosthetic restorations. Until date, no studies have been described investigating immediate loading of implants in the aesthetic zone using three-dimensional DPS-printers and their impact on patient-satisfaction. * Main research question The purpose of this one-year prospective case series study is to perform an assessment of patient-reported outcomes of single-tooth implants with immediate provisionalization using three-dimensionally printed provisional crowns. * Design (including population, confounders/outcomes) The study design is a prospective, single-arm observational study for evaluation of 30 patients with a failing tooth in the maxillary aesthetic region to be treated with an implant-supported provisional and definitive restoration by means of a provisional and definitive crown. Outcomes: registration of time/complications during the diagnostic/planning/manufacturing process, evaluation of clinical and radiographical performance and aesthetic outcome. * Expected results Satisfying results for patients and professionals (VAS-scores and PES/WES-scores)

You may qualify if…

• The patient is 18 years or older;
• The implant region is an incisor (central or lateral), cuspid or first bicuspid in the maxilla; the adjacent teeth are natural teeth;
• Sufficient healthy and vital bone after alveolar ridge preservation to insert a dental implant with a minimum length of 10 mm and at least 3.5 mm in diameter with initial stability > 45 Ncm;
• The implant site must be free from infection;
• Adequate oral hygiene (modified plaque index and modified sulcus bleeding index ≤ 1);
• Sufficient mesio-distal, bucco-lingual, and interocclusal space for placement of an anatomic crown;
