Complications of Expanded Polytetrafluoroethylene (e‐PTFE) Facial Implant
Dermatologic Surgery, 2001Co-Authors: Harold J. BrodyAbstract:Implantation of the expanded polytetrafluoroethylene (e-PTFE) Implant to achieve correction of nasolabial folds or thinning lip has been fraught with complications in spite of patient acceptance since its introduction in 1997. The four most frequent postoperative complications are extrusion, movement, infection, and swelling. In examination of 86 insertions of the 3.2 mm tubular Implants, these sequelae are generally manageable for the physician and patient. If the patient understands possible courses of healing, both physician and patient satisfaction may be achieved.

Improvement of biohistological response of Facial Implant materials by tantalum surface treatment
Maxillofacial Plastic and Reconstructive Surgery, 2019Co-Authors: Mohammed Mousa Bakri, Sung Ho Lee, Jong Ho LeeAbstract:Background A compact passive oxide layer can grow on tantalum (Ta). It has been reported that this oxide layer can facilitate bone ingrowth in vivo though the development of bone-like apatite, which promotes hard and soft tissue adhesion. Thus, Ta surface treatment on Facial Implant materials may improve the tissue response, which could result in less fibrotic encapsulation and make the Implant more stable on the bone surface. The purposes of this study were to verify whether surface treatment of Facial Implant materials using Ta can improve the biohistobiological response and to determine the possibility of potential clinical applications. Methods Two different and commonly used Implant materials, silicone and expanded polytetrafluoroethylene (ePTFE), were treated via Ta ion Implantation using a Ta sputtering gun. Ta-treated samples were compared with untreated samples using in vitro and in vivo evaluations. Osteoblast (MG-63) and fibroblast (NIH3T3) cell viability with the Ta-treated Implant material was assessed, and the tissue response was observed by placing the Implants over the rat calvarium ( n = 48) for two different lengths of time. Foreign body and inflammatory reactions were observed, and soft tissue thickness between the calvarium and the Implant as well as the bone response was measured. Results The treatment of Facial Implant materials using Ta showed a tendency toward increased fibroblast and osteoblast viability, although this result was not statistically significant. During the in vivo study, both Ta-treated and untreated Implants showed similar foreign body reactions. However, the Ta-treated Implant materials (silicone and ePTFE) showed a tendency toward better histological features: lower soft tissue thickness between the Implant and the underlying calvarium as well as an increase in new bone activity. Conclusion Ta surface treatment using ion Implantation on silicone and ePTFE Facial Implant materials showed the possibility of reducing soft tissue intervention between the calvarium and the Implant to make the Implant more stable on the bone surface. Although no statistically significant improvement was observed, Ta treatment revealed a tendency toward an improved biohistological response of silicone and ePTFE Facial Implants. Conclusively, tantalum treatment is beneficial and has the potential for clinical applications.

autogenous bone block grafting provides Facial Implant tissue stability long term
Clinical Implant Dentistry and Related Research, 2017Co-Authors: Fernando Verdugo, Agurne Uribarri, Antonio DaddonaAbstract:Background Mucosal recession (MR) and bone loss can compromise anterior Implant esthetics. Purpose To evaluate tissue stability and clinical outcomes of anterior Implants augmented with autogenous block transplants long-term. Materials and Methods This prospective cross-sectional clinical study analyzed Facial tissue recession of anterior Implants augmented with autogenous bone blocks and compared them to adjacent teeth in forty patients 52 months post-augmentation. Clinical parameters, MR and Implant transparency, were assessed at delivery and follow-up. The hypothesis is that the Facial mucosa of augmented Implant sites is more resistant to trauma than the gingival margins of adjacent teeth. Results Teeth were seven times more likely to present a Facial recession than adjacent augmented Implants at 52-month follow-up (RR: 7; P < .001; 95%CI: 2.7-18.0). Augmented Implant sites were six times more likely to present “no-tissue-recession” than adjacent teeth (RR: 6.2; P < .001; 95%CI: 2.4-15.7). Mean tooth Facial tissue recession was significantly higher than adjacent Implants, 1.18 ± 1.05 mm (range: 0-3.5 mm) vs. 0.06 ± 0.2 mm (95%CI: 0.8-1.5; P < .0001). Thick biotype teeth were 2 times more resistant to recession than thin biotype teeth (RR: 2.03; P = .03; 95%CI: 1.2-3.5). Implant success rates were 100%. Lack of transparency and MR at Facial Implant sites lasted an average of 52 months and up to 144 without signs of inflammation or pocket formation regardless of the individual's biotype. Facial bone thicknesses of 2.2 mm seem optimal for tissue stability. Conclusions Autogenous bone block augmentation with staged Implant placement seems to be a predictable, short-healing, reconstructive protocol in the esthetic zone maintaining stable peri-Implant tissues long-term. Implant augmented sites seem more resistant to develop a recession than adjacent teeth.
