Management of an Implant Complication in Maxillary Anterior Region | Implant

By Chao Ji 311

This case report describes the management of an implant complication in maxillary anterior region for a 20-year-old patient. Two ailing implants were iatrogenically placed at sites 22 and 23, which resulted in significant hard and soft tissue defects. After atraumatical removal of both implants, a series of combined hard and soft tissue augmentation procedures were performed to achieve a satisfactory outcome with two implant-supported screw-retained crowns. Started with a free gingival graft to increase the amount of keratinized gingiva, guided bone regeneration was subsequently performed to make it possible for two narrow implants to be placed 8 months later. Another free gingival graft was done at the time of stage 2 implant surgery. In order to reduce the dark triangle between the provisional crowns, papilla regeneration microsurgery was performed. Two final screw-retained zirconia implant crowns were delivered and the outcome remained satisfactory and stable at three-year review.

Full Arch Digital Rehabilitation | Implant

By Dr. Tommy Fung 39

Digital implant planning plays an essential role in the execution of full-arch rehabilitation. In fully edentulous cases, additional challenges come from mucosal polymorphism. In this case, delicate duplication of radiographic / surgical guide intaglio and meticulous bite control allowed close-to-identical positional replication. Implant positioning was driven by anatomy to reduce the surgical risk to important neurovascular structure and to avoid bone defect. Selection of screw retained abutment with suitable angulation resulted in proper mucosal exit, hence the harmonious emergence profile development important for hygienic reasons. The fine-tuned implant position, angulation and depth were translated to clinical reality through a series of printed surgical guides. Permanent prosthesis was constructed based on accurate intraoral scan with appropriately designed scan gauge and specific scanning protocol. Professional digital laboratory support brought natural looking dentition back to life.

2-visit Dental Implant Treatment with the Help of Digital Dentistry | Implant

By Andrew Ma 312

Using intra-oral scanning and dental CAD-CAM technology, dental implant treatment can be completed in just two patient appointments with predictable outcome. In this particular case, after the implant was placed, the position of the implant was determined using intra-oral scanning with a scan body. The implant crown was designed and fabricated. When the implant was ready to restore, the second stage surgery was preformed by making an incision on the palatal side of the implant while preserving the inter-proximal papilla. The final screw-retained implant crown was tried-in and delivered during the same appointment. The flap was rolled under the buccal contour of the implant crown and no suture was required. This method offers several advantages. It reduces appointment times. The principle of "one abutment, one time" is achieved. Since the crown is delivered right after the second stage surgery, the soft tissue always conforms to the intended emergence profile.
