The treatment involves using a tunneled coronally advanced flap to obtain access for defect de-bridement, root instrumentation, graft placement, and tissue advancement for root coverage. A connective tissue graft is secured to the two teeth flanking the infrabony defect using two subperi-osteal sling sutures to create a buccal soft tissue wall and tent up the papilla overlying the defect, providing and maintaining the necessary space for biomaterial and clot stability.

It is known that addressing both the quantity and quality of soft tissue is crucial for the long-term success and esthetics of implants. This report introduces a novel technique for peri-implant phenotype modification following bone augmentation, which combines a modified onlay graft (MOG) with an apically positioned flap (APF) performed simultaneously with implant placement. Two clinical cases are presented to demonstrate this approach, highlighting the restoration of the soft tissue environment through a single surgical intervention. The technique resulted in successful outcomes, including increased vestibular depth, keratinized tissue width, and vertical soft tissue volume. The MOG technique effectively manages soft tissue in post-bone augmentation scenarios, providing an ideal peri-implant phenotype and leading to stable, esthetic, and functional implant restorations.

CP-AL distance may be a non-invasive representative for the classic contact point-bone crest distance (CP-BC) which is being used to determine the presence of interdental papilla as per existing knowledge. Total 195 systemically healthy patients were recruited with age ranging 18-45years in this cross-sectional study. Clinical parameters included were CP-BC, CP-AL, contact point-papilla tip (CP-PT), contact point- interproximal cementoenamel junction (CP-iCEJ), and periodontal phenotype (PP). The height of black triangle (CP-PT) and presence/absence of papilla, both were statistically significantly and positively correlated with CP-BC and CP-AL distance. The statistically significant and positive association was also observed between CP-AL distance and height of black triangle. The results suggested that increase in 0.57mm of CP-AL distance resulted in 1unit increase in measurement of height of black triangle. Furthermore, receiver-operating characteristic (ROC) analysis showed the threshold value of CP-AL distance at or above which there would be presence of black triangle was 3.5mm.
