Prosthetic management of malpositioned implant using custom cast abutment

Abstract

Two cases are reported with malpositioned implants. Both the implants were placed 6–7 months back. They had osseointegrated well with the surrounding bone. However, they presented severe facial inclination. Case I was restored with custom cast abutment with an auto polymerizing acrylic gingival veneer. Case II was restored with custom cast UCLA type plastic implant abutment. Ceramic was directly fired on the custom cast abutments. The dual treatment strategy resulted in functional and esthetic restorations despite facial malposition of the implants.

Dynamic UCLA for aesthetic rehabilitation on implant in a patient with special needs: A 4-year follow-up case report

“…Poorly positioned implants are a preventable problem. Meticulous planning with diagnostic waxing, surgical guide, diagnostic imaging and good communication between surgeons, prosthodontists and the laboratory could prevent this problem (Chatterjee et al, 2015;Giannakopoulos et al, 2017). In this case report, the cognitive and motor disabilities of the patient, and local surgical limitations influenced the implant installation, however, complementary surgical procedures or long treatments were not indicated.…”

“…Alongside this successful story there are complications (Camargos et al, 2012) that challenge the prosthodontist to meet patient expectations (Chatterjee et al, 2015;Giannakopoulos et al, 2017). Commonly these complications are due to poor planning and poor communication between surgeon and prosthodontists, which might result in a common and avoidable complication: the three-dimensional implant positioning error (Chatterjee et al, 2015).…”

Long‐term survival analysis of standard‐length and short implants with multifunctional abutments

“…Previously reported treatment modalities for malpositioned dental implants involve the use of hybrid prostheses, customised and angled abutments, and milled or cast metal bars for totally edentulous rehabilitation . The use of angled abutments may increase the stress transferred to supporting implants and adjacent bone, with direct effects on the prosthesis .…”

“…The use of angled abutments may increase the stress transferred to supporting implants and adjacent bone, with direct effects on the prosthesis . In addition, only moderate malpositioning can be treated using these alternatives, and few reports, most of which are case reports and case series, have described the performance of such angled components …”

Prosthetic Rehabilitation of Deeply Placed Implant

“…During treatment planning for restorative phase, nonoptimal implant position is seen in three geometric planes, that is, facial palatal angulation and depth and position of the implant. 5 The location, length, and angulation are the paramount factors for optimal implant supported prosthesis.…”
