Treatment of Labial Soft Tissue Recession Around Dental Implants in the Esthetic Zone Using Guided Bone Regeneration With Mineralized Allograft: A Retrospective Clinical Case Series

Alloplastic dental implants are currently the best way to replace lost teeth. In order to achieve good function and prognosis of dental implants, having bone and soft tissue to support them is necessary. When the amount of bone left is not enough to ensure the outcome of the implant, techniques such as shorts implants, zygomatic implants, or guided bone regeneration have been used. Even though autologous bone is mostly the “gold standard,” other biomaterials such as xenografts have led to the reduction of the morbidity of treatments and to the improvement of the regeneration technique outcomes. We present a clinical case of severe atrophy of the maxilla in which we used different types of biomaterials: heterologous cortical lamina, xenograft and autologous bone, and microscrews.

Purpose: The usage of non-resorbable membranes in guided bone regeneration (GBR) has been widely described in the literature as a valid treatment option to address horizontal and vertical alveolar bone defects in implant dentistry. It’s also consensual that factors such as the stability of the membrane, the surgical technique, the gingival biotype, the blood supply and the postoperative care, play an essential role on the success and predictability of the augmentation. The purpose of this article is to describe a clinical case where a non-resorbable membrane was used following the immediate placement of two dental implants in the maxilla. Case report: This case report describes a clinical case where the upper right lateral incisor and the upper right canine where extracted followed by the immediate placement of two dental implants. A Titanium membrane was used on the socket of the lateral incisor to stabilize a xenograft placed in the buccal alveolar defect. The membrane used was directly connected to the implant connection which facilitated its surgical placement stability and removal. After 4 months, upon removing the membrane, it was evident that there was a satisfactory horizontal bone regeneration. The impressions stage followed and two screw-retained porcelain bonded crowns were finally fitted. Conclusion: The authors have found that the usage of a non-resorbable membrane allowed a predictable horizontal bone augmentation in this clinical case. The results obtained were quite rewarding for both clinicians and patient and remain functional and stable as confirmed with the two-year clinical follow up and CBCT scan results.

Abstract The term retrograde peri-implantitis has been commonly used to describe lesions in the periapical region of dental implants. There are very few reports on this condition, and the exact etiology and pathogenesis are subject to speculation. Management of retrograde peri-implantitis is even more scarcely discussed in the literature. The current article briefly reviews the literature on this subject and presents a case report of retrograde peri-implantitis. Special emphasis is placed on the management of the condition, and different strategies are critically evaluated. If the fixture is stable despite bone loss in the periapical region, it is suggested that surgical debridement be carried out with the use of a surface antiseptic like chlorhexidine. Also all possible efforts should be made to prevent damage to the implant surface. Bone loss due to this condition may be regenerated on the basis of the principle of guided bone regeneration.

Background and Objective: Guided bone regeneration allows new bone formation in anatomical sites showing defects preventing implant rehabilitation. Material and Methods: The present case series reported the outcomes of five patients treated with customized titanium meshes manufactured with a digital workflow for achieving bone regeneration at future implant sites. A significant gain in both width and thickness was achieved for all patients. Results: From a radiographic point of view (CBTC), satisfactory results were reached both in horizontal and vertical defects. An average horizontal gain of 3.6 ± 0.8 mm and a vertical gain of 5.2 ± 1.1 mm. Conclusions: The findings from this study suggest that customized titanium meshes represent a valid method to pursue guided bone regeneration in horizontal, vertical or combined defects. Particular attention must be paid by the surgeon in the packaging of the flap according to a correct method called the “poncho” technique in order to reduce the most frequent complication that is the exposure of the mesh even if a partial exposure of one mesh does not compromise the final outcome of both the reconstruction and the healing of the implants.

Purpose – The purpose of this paper is to describe two different approaches for manufacturing pre-formed titanium meshes to assist prosthetically guided bone regeneration of atrophic maxillary arches. Both methods are based on the use of additive manufacturing (AM) technologies and aim to limit at the minimal intervention the bone reconstructive surgery by virtual planning the surgical intervention for dental implants placement. Design/methodology/approach – Two patients with atrophic maxillary arches were scheduled for bone augmentation using pre-formed titanium mesh with particulate autogenous bone graft and alloplastic material. The complete workflow consists of four steps: three-dimensional (3D) acquisition of medical images and virtual planning, 3D modelling and design of the bone augmentation volume, manufacturing of biomodels and pre-formed meshes, clinical procedure and follow up. For what concerns the AM, fused deposition modelling (FDM) and direct metal laser sintering (DMLS) were used. Findings – For both patients, a post-operative control CT examination was scheduled to evaluate the progression of the regenerative process and verify the availability of an adequate amount of bone before the surgical intervention for dental implants placement. In both cases, the regenerated bone was sufficient to fix the implants in the planned position, improving the intervention quality and reducing the intervention time during surgery. Originality/value – A comparison between two novel methods, involving AM technologies are presented as viable and reproducible methods to assist the correct bone augmentation of atrophic patients, prior to implant placement for the final implant supported prosthetic rehabilitation.

Abstract Background: The aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using 3D replicas. Methods: Ten patients underwent teeth autotransplantation with or without GBR. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during two years following up, which were transplanted into fresh molar sockets by using 3D replicas, and GBR when it is necessary. Results: The average extra-oral time of donor tooth had been shortened to 1.65 min when used the 3D replica. Some probing depth of the transplanted tooth were deeper than 3 mm at 4 or 5 weeks temporarily. And one patient felt slight sensitive when chewing with soft food at 4 weeks, then disappeared. The clinical examination of the autotransplantation teeth during one year follow-up showed no sign of failure. Conclusions: The tooth autotransplantation using 3D replica with or without GBR is an effective method which can reduce the extra-oral time of the donor teeth and may result in less failure.
