## TL;DR

This case series explores the success of placing dental implants immediately after tooth extraction without cutting bone, showing promising stability and healing outcomes.

## Contribution

The study introduces a novel approach to immediate dental implant placement without osteotomy, using specific implant design and healing abutments.

## Key findings

- Implants achieved high insertion torque and ISQ values, indicating good primary stability.
- Bone remodeling was minimal (0.35 mm) from implant placement to restoration.
- RFA values increased over time, suggesting successful osseointegration.

## Abstract

This case series evaluates healing parameters of immediately placed implants in fresh extraction sockets without osteotomies. It examines resonance frequency analysis (RFA) trends and radiographic bone changes from placement to prosthetic restoration.

The study reports on eight patients with 10 implants using a self‐tapping, knife‐shaped implant with progressive thread design and anatomical healing abutments. RFA values and standardized radiographs were recorded at three time points from placement to prosthetic restoration.

Implants were placed in molar, premolar, and incisor sockets. All implants achieved insertion torque greater than 35 Ncm and high ISQ values. The median reported bone remodeling was 0.35 mm from implant placement to definitive restoration. RFA revealed a median of 64 ISQ buccolingually and 74 ISQ mesiodistally at placement, increasing to 76 ISQ buccolingually and 82 ISQ mesiodistally pre‐prosthetically.

The findings suggest that immediate dental implants placed without osteotomies in select anatomical conditions can achieve successful osseointegration and functional stability. However, given the small sample size, further studies with larger cohorts are necessary to validate these results.

Immediate implants can achieve primary stability without osteotomy in select cases.Anatomical healing abutments may enhance tissue volume preservation and emergence profile.Further studies with larger samples are required to validate these preliminary findings.
