TL;DR
SST offers better outcomes than CIP without compromising implant survival, but it is technique-sensitive and demands careful execution, and further high-quality, long-term studies are needed to support clinical standardization.
Abstract
STATEMENT OF PROBLEM
The socket shield technique (SST) has been proposed to preserve the buccal bone plate and peri-implant soft tissues during immediate implant placement, potentially improving esthetic outcomes. While its biological rationale has been well supported, comparative evidence with conventional protocols remains heterogeneous.
Purpose
The purpose of this systematic review was to compare the clinical and radiographic outcomes of SST and conventional immediate implant placement (CIP) by assessing implant survival, marginal bone loss (MBL), buccal bone thickness, pink esthetic score (PES), soft tissue changes, and complications.
MATERIAL AND
Methods
A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines across 6 electronic databases up to July 2025. Comparative clinical studies with a minimum follow-up of 3 months evaluating SST versus CIP were included.
Results
Eleven studies involving 423 implants were included. Implant survival rates exceeded 95% in both groups. SST showed significantly less buccal and crestal bone loss and consistently higher PES scores across short- and long-term follow-up. The technique improved peri-implant soft tissue contours and reduced midfacial recession. SST-related complications, such as mobility or exposure, were infrequent and mostly linked to surgical error or poor patient selection.
Conclusions
SST offers better outcomes than CIP without compromising implant survival. However, it is technique-sensitive and demands careful execution. Digital workflows and guided shield preparation may enhance predictability, but further high-quality, long-term studies are needed to support clinical standardization.
Background/Objectives: Vestibular socket therapy (VST) is a minimally invasive technique for immediate implant placement (IIP) in compromised extraction sockets that reconstructs the deficient buccal plate while preserving the crestal soft tissue. Despite growing clinical adoption, the randomized evidence on its predictability and biological performance remains limited. Methods: Following PRISMA 2020 and prospectively registered in PROSPERO (CRD420261288724), PubMed/MEDLINE and EMBASE were searched to January 2026 for randomized controlled trials (RCTs) evaluating VST with IIP. Risk of bias (RoB 2) and certainty of evidence (GRADE) were assessed. Final follow-up buccal bone plate thickness was pooled using a random-effects model; trials comparing variations within VST were reported narratively but not pooled. Results: Seven RCTs (186 participants) were included; implant survival was 99.5%, with no shield exposure, peri-implantitis, or dehiscence. Meta-analysis of the three trials comparing VST against a distinct alternative technique showed no significant between-group difference in final buccal bone plate thickness at any level: crestal +0.24 mm (95% CI−0.13 to 0.61; I2 = 45%), mid-root +0.32 mm (−0.45 to 1.09; I2 = 82%), or apical +0.19 mm (−0.48 to 0.87; I2 = 67%). VST showed minimal mid-facial recession, stable papillae, and Pink Esthetic Scores of 10.29–13.17. Certainty was very low for all outcomes. Conclusions: VST achieved high implant survival and favorable soft tissue and esthetic outcomes but did not significantly outperform comparator techniques in buccal bone plate thickness, with very low certainty. Adequately powered, independent trials with longer follow-up are needed.

Short dental implants represent a valid, minimally invasive alternative to bone augmentation in appropriately selected patients and depend on modern nano-structured implant surfaces, adequate prosthetic splinting, bone quality assessment, and rigorous peri-implant maintenance.

While DO provides the greatest vertical bone gain, the GBR techniques might be a more clinically practical option, however, future well-planned RCTs to identify effective vertical bone augmentation techniques are still warranted.
AIM
To compare the clinical outcomes of digitally assisted immediate implant placement in the posterior mandible using immediate (Type A) and delayed (Type C) loading protocols.
METHODS
Eighty-two patients requiring five-unit fixed partial dentures supported by three implants were consecutively enrolled. All cases were planned using a fully digital workflow integrating CBCT, intraoral scanning, and static computer-guided surgery. Only implants achieving adequate primary stability (insertion torque ≥25 Ncm and/or ISQ ≥60) were included. Patients were assigned to either immediate or delayed loading protocols. Implant survival, marginal bone loss (MBL), plaque index (PI), bleeding on probing (BOP), and probing depth (PD) were evaluated over variable follow-up periods according to the timing of patient enrollment and treatment completion.
RESULTS
A total of 246 implants were placed, yielding an overall survival rate of 97.5% with no significant differences between loading protocols. Mean MBL was 0.7 mm and remained comparable between groups. Peri-implant parameters, including PI, BOP, and PD, were stable throughout follow-up. Regression analysis identified restorative angles >30° as the only significant predictor of increased MBL.
CONCLUSION
Digitally guided immediate implant placement in the posterior mandible demonstrated high survival rates and favorable peri-implant outcomes with both Type A and Type C loading protocols.
CLINICAL SIGNIFICANCE
Type A loading may provide a predictable and time-efficient alternative to conventional delayed loading without compromising clinical outcomes.

OBJECTIVE
Reconstruction of severe vertical and horizontal alveolar ridge defects remains a clinical challenge in implant dentistry. The Khoury bone plate technique is widely used; however, graft resorption and limited graft containment may affect outcomes. This study aimed to evaluate the clinical outcomes of the Composite Cortical Plate Grafting (CCPG) technique compared with the Khoury bone plate technique. This retrospective comparative clinical study included 64 ridge augmentation procedures performed using either a CCPG technique (n=32) or the Khoury bone plate technique (n=32). The dual-layer approach involved cortical plate fixation, composite grafting with autogenous bone and xenograft, followed by an additional xenograft layer and pericardium membrane coverage. Bone gain was assessed clinically and radiographically. Graft resorption was evaluated based on radiographic observations during follow-up. Implant success was defined by clinical stability and absence of complications. The follow-up period ranged from 6 to 12 months.
RESULTS
The CCPG technique showed greater bone gain and improved graft stability compared with the Khoury technique. Lower graft resorption and higher implant placement success rates were observed in the CCPG group (93.7% versus 75%). Complication rates were lower in the CCPG group.
CONCLUSIONS
The findings suggest that the CCPG technique may provide favorable outcomes in terms of bone gain and graft stability compared with the Khoury technique. This approach represents a modification of established ridge augmentation methods and may be considered in the management of complex alveolar defects.
