Abstract. This study aimed to evaluate the stress distribution through the photoelastic method in implant-retained palatal obturators prostheses. Two photoelastic models with bucco-sinusal communication were fabricated, one model without implants and another with two parallel implants and one tilted in the molar region. A conventional obturator prosthesis and five implant-retained obturators dentures with different attachment systems were fabricated: OR, three individualized O-rings; BC, bar clip; BOC, implants splinted by bars associated with two O-rings positioned at the center of the bar; OD, implants splinted by bars associated with two O-rings positioned in distal cantilever; and BOD, implants splinted by bars with clips associated with two O-rings positioned in distal cantilever. Each assembly (model/attachment system/prosthesis) was positioned in a circular polariscope and a load of 100 N was applied on each implant. The results were obtained by observing the photographic record of the tensions in the photoelastic models resulting from the application of load. It can be observed that a larger amount of stress fringes on BC system. It was concluded that the attachment system has a direct influence on the stress distribution of implant-retained obturator prostheses, with the three individualized O-rings exhibiting the lowest stress values, and tilted implants presented a biomechanical behavior similar to parallel implants. © The Authors.Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

“…Although the use of composite flaps in the maxillectomy patient has been well reported, there is still much debate about the best flap to use in a specific circumstance, and this often comes down to patient fitness as well as the preference and experience of the surgical team. The use of composite flaps can provide much needed bony support for cosmetic facial support and also provide bone for subsequent or immediate osseointegrated implant insertion to facilitate dental rehabilitation …”

“…The use of composite flaps can provide much needed bony support for cosmetic facial support 5 and also provide bone for subsequent or immediate osseointegrated implant insertion to facilitate dental rehabilitation. 6 The subsequent provision of a dental prosthesis in these high-level maxillectomy cases, although possible, is often not provided due to the difficulties in tolerating a conventional dental prosthesis after such surgeries, lack of prosthodontic expertise or funding for dental implants, or lack of patient suitability with the result that very few patients ultimately receive an implant-based rehabilitation. 7 When any type of prosthesis is required in this group of patients, the use of osseointegrated implants provide a much-needed foundation for its retention, stability, and overall patient acceptance.…”

Background Zygomatic implants can provide excellent remote anchorage to support the prosthetic rehabilitation of patients treated for maxillary and midfacial tumors. Methods Patients who underwent zygomatic implant placement by the author between 2006 and 2016 as part of their oncology treatment were followed prospectively. Results Forty‐nine consecutively treated patients received 131 zygomatic implants of which 9 failed and were removed from 4 patients; 24 patients (49%) received radiotherapy either before or after implant insertion. The overall 12‐month survival estimate was 94% and the 60‐month estimate was 92%. Conclusions The use of zygomatic implants in the management of maxillary and midfacial malignancy is a predictable prosthetic treatment modality to support complex oral and facial prostheses. Their use with or without free tissue transfer can provide effective prosthetic rehabilitation with high implant survival irrespective of the timing of placement or the need for adjuvant radiotherapy. Clinical Significance Zygomatic Implants provide an excellent platform for the restoration of the dentition and facial structures affected by maxillary and midfacial malignant disease.

“…With an osseous component, osseointegrated implants for future dental rehabilitation can be pursued. 13 Several different osseous flaps have been used and include the fibular osteocutaneous flap, [13][14][15][16][17][18][19] iliac crest flaps, 20 and scapular flaps. [21][22][23] Studies on speech outcomes have shown that maxillary reconstruction results in satisfactory speech 22,24,25 and normal intelligibility.…”

Purpose: Treatment of maxillary defects, whether by prosthetic rehabilitation or surgical reconstruction, should aim to restore speech function and resonance balance. With the advent of technology and changing clinical practices related to maxillary defect management, speech outcomes need to be evaluated and compared in order to determine efficacy of differing approaches. Materials and Methods: One hundred and four patients across three treatment groups for maxillary defects were included: 38 patients who were treated with maxillary obturators (OBT group), 39 patients who were treated with a standard fibular free flap reconstruction that did not involve digital planning of the reconstruction (Standard group) and 27 patients who were reconstructed using a digitally planned surgical design and simulation fibular free flap reconstruction (SDS group). Speech assessments were completed to assess word and sentence intelligibility, resonance balance and aeromechanical orifice estimation among these three groups. Assessments included the Computerized Assessment of Intelligibility of Dysarthric Speech (C-AIDS), nasalance scores via the Nasometer and palatopharyngeal orifice area via the PERCI-SARS. Results: Significant differences were found in word intelligibility between the SDS and the Standard groups (p =.035) and on nasalance scores between the SDS and the OBT groups (p=.027). Conclusions: Patients treated with digital reconstruction (SDS) had better speech outcomes than the other two treatment groups, whose mean scores on certain speech variables were not within normal limits. Speech outcomes in the SDS group were consistently within the normal range across all measured speech variables.
