“…On the other hand, the laboratory cost associated with the presented CAD/CAM compound prosthesis is significantly reduced when compared to a prosthesis that has been designed with a substructure and individual cementable crowns on top of the substructure. [15][16][17] Another limitation of the presented CAD/CAM compound prosthesis is the unknown amount of retention associated when cementing a complete-arch zirconia superstructure to a titanium milled bar by using a temporary cement. Garg et al 29 indicated that the amount of retention obtained when a temporary cement is used over a milled abutment ranges between 333.86 and 394.62 N. However, their study was conducted on single abutmentsupported crowns.…”

The computer-assisted design/computer-assisted manufactured compound prosthesis involves designing and milling a cement-retained prosthesis over milled titanium bars. In the presented clinical case report, a diagnostic wax pattern was made to assess esthetics, contours, and occlusion. A total of eight maxillary root-form implants were restored by following the combined prosthesis design concept. The mandibular arch was restored with a screwretained implant-supported zirconia fixed prosthesis. A milled polymethyl methacrylate (PMMA) maxillary interim prosthesis was fabricated to intraorally confirm the diagnostic wax pattern. The interim PMMA prosthesis was then scanned, and three screw-retained titanium milled bars were designed that provided the substructure of the definitive restoration. A cement-retained milled zirconia prosthesis was then designed and fabricated. The zirconia prosthesis provided the superstructure of the definitive complete-arch restoration. After confirming esthetics, phonetics, occlusion, and accessibility for oral hygiene, the superstructure was cemented with temporary cement to enable retrievability.

“…15 In clinical situations where severe bone resorption precludes implant placement at an ideal prosthetic position, some authors have suggested the fabrication of individual crowns cemented on an implantsupported substructure. [15][16][17] The limitation of this treatment modality is the high cost associated with it.…”

“…Rehabilitating prosthetically challenging implants poses a significant challenge for restorative dentists, laboratory technicians, and patients, especially in the critical maxillary smile zone. Prosthetic adjustments, surgical corrections, or a combination of both may be necessary in such cases [3][4][5].…”

Rehabilitation of Malpositioned Implant in the Anterior Region With Customized Abutment

The misplacement of implants represents an unfavorable complication in dental implant prostheses. Numerous instances necessitating restorative intervention, colloquially termed "rescue cases," encompass either novel occurrences or reconstructions of irreversible implant scenarios. A viable solution for addressing these prosthesis-related challenges is using cementable options. This issue is directly linked to improperly placed implants, which dentists find challenging to rectify due to the absence of angle-correcting abutments from manufacturers. In such situations, the preferred treatments involve either Implant Innovations' universal castable long abutment (UCLA) (Palm Beach Gardens, Florida, United States) or a customized abutment fashioned from the titanium alloy impression coping for the Core-Vent implant (Paragon, Calabasas, California, United States). The Department of Prosthodontics received a referral for a patient with an anterior implant that had been misplaced and required rehabilitation. This case report outlines the chosen treatment approach for an implant situated buccally.

Custom abutments on tilted implants in the maxilla: A clinical report

et al. 2020

View full text Add to dashboard Cite

The aim of this work is to describe a case of severe disparallelism between two implants supporting a cement-retained bridge, placed in the maxilla, employing two custom-angled abutments. Fractured abutment screw and fractured abutment involved two implant restorations in the maxilla. Once prosthetic components have been removed, a new prosthetic rehabilitation has been planned. The divergence between the implants was measured, obtaining an angle of divergence of 39°. Then, two custom-angled titanium abutments and two metal-ceramic splinted crowns were realized.
