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.

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.

Autologous Bone

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.

A variety of techniques have been documented for the recovery of bone loss in areas where rehabilitation with dental implants is planned. The loss of teeth is followed by the loss of height and thickness of the bone too, precluding the installation of dental implants. The premature bone loss in this region can also cause pneumatization of the maxillary sinuses. So, the corrections of these defects are a real challenge for dentists and oral surgeons. The technique of segmental osteotomy with bone interposition graft has proven to be a viable option to solve this problem. This clinical case report describes the successful application of the technique in the treatment of decreased vertical dimension in the posterior area of the maxilla, where 7 months later 4 dental implants were installed. Two dental implants of 13 mm, and two dental implants of 11 mm, demonstrating success with bone height that was achieved in the case, making the use of this technique very sustainable in bone loss of posterior area of the maxilla with pneumatized maxillary sinuses.

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.

Background. The placement of an implant in a previously infected site is an important etiologic factor contributing to implant failure. The aim of this case report is to present the management of retrograde peri-implantitis (RPI) in a first maxillary molar site, 2 years after the implant placement. The RPI was treated using an air-abrasive device, Er,Cr:YSGG laser, and guided bone regeneration (GBR). Case Description. A 65-year-old Caucasian male presented with a draining fistula associated with an implant at tooth #3. Tooth #3 revealed periapical radiolucency two years before the implant placement. Tooth #3 was extracted, and a ridge preservation procedure was performed followed by implant rehabilitation. A periapical radiograph (PA) showed lack of bone density around the implant apex. The site was decontaminated with an air-abrasive device and Er,Cr:YSGG laser, and GBR was performed. The patient was seen every two weeks until suture removal, followed by monthly visits for 12 months. The periapical X-rays, from 6 to 13 months postoperatively, showed increased bone density around the implant apex, with no signs of residual clinical or radiographic pathology and probing depths ≤4 mm. Conclusions. The etiology of RPI in this case was the placement of an implant in a previously infected site. The use of an air-abrasive device, Er,Cr:YSGG, and GBR was utilized to treat this case of RPI. The site was monitored for 13 months, and increased radiographic bone density was noted.
