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

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.

Treatment and study plan

Conventional Flap Implant Placement

Procedure

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.

Flapless guided implant

Procedure

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.

Primary outcomes

  1. Marginal Bone Loss

    Time frame: baseline, 3 months, 6 months

    CBCT assessment

Secondary outcomes

  1. Implant Stability ISQ

    Time frame: baseline, 3 months, 6 months

    Implant stability was assessed as a secondary outcome using Resonance Frequency Analysis (RFA), which provides an objective and non-invasive measurement of implant stability expressed as the Implant Stability Quotient (ISQ).

  2. Postoperative Pain Assessment VAS scale 0-10

    Time frame: baseline, Day 2 Day 3 Day 4 Day 5

    VAS scale 0-10
