Qualitative and Quantitative Assessment of Marginal Bone Loss Following Flapless Guided Versus Conventional Implant Placement

2026年6月17日更新者：Gulf Medical University

Qualitative and Quantitative Assessment of Marginal Bone Loss Following Flapless Guided Versus Conventional Implant Placement Using Cone Beam Computed Tomography - A Split-Mouth Randomized Controlled Trial.

Marginal bone preservation is an important determinant of long-term implant success. Conventional flap implant placement provides direct visualization of the surgical site but may disturb the periosteal blood supply and contribute to early crestal bone remodeling.

Flapless guided implant placement is a minimally invasive approach that aims to preserve soft tissue architecture and vascular integrity. CBCT allows three-dimensional evaluation of peri implant bone levels, including mesial, distal, buccal, and lingual aspects.

Aim: The aim of this study was to compare flapless guided implant placement with conventional flap implant placement in terms of marginal bone loss, implant stability, postoperative pain, and soft-tissue healing.

参与者组/臂	干预/治疗
实验性的：Flapless Guided Implant Placement	程序：Flapless guided implant a minimally invasive dental implant procedure where a surgical guide, often created using advanced imaging techniques like cone-beam computed tomography (CBCT) and computer-aided design (CAD), directs the precise placement of dental implants without the need for traditional flap elevation.
实验性的：Conventional Flap Implant Placement	程序：Conventional Flap Implant Placement manually raising the gingival tissue during dental implant surgery, this surgical procedure involves the placement of a dental implant directly into the alveolar or basal bone during a single session followed by the placement of a healing abutment without the use of surgical guides or advanced technology.
