The traditional methods of metallic bone implants are often dense and suffer from adverse reactions, biomechanical mismatch and lack of adequate space for new bone tissue to grow into the implant. The objective of this study is to evaluate the customized porous cranial implant with mechanical properties closer to that of bone and to improve the aesthetic outcome in cranial surgery with precision fitting for a better quality of life. Two custom cranial implants (bulk and porous) are digitally designed based on the Digital Imaging and Communications in Medicine files and fabricated using additive manufacturing...

The modification of biomaterials approved by the Food and Drug Administration could be an alternative to reduce the period of use in humans. Porous bioceramics are widely used as support structures for bone formation and repair. This composite has essential characteristics for an implant, including good mechanical properties, high chemical stability, biocompatibility and adequate aesthetic appearance. Here, three-dimensional porous scaffolds of Al2 O3 containing 5% by volume of ZrO2 were produced by the replica method...

The evolution of breast reconstructive surgery keeps pace with the evolution of breast oncologic surgery. The reconstructive choice should always balance the optimal local control of disease and the best cosmetic result, reflecting an informed decision that is shared with the patient, who is always at the center of the decision-making process. Implant-based breast reconstruction following mastectomy represents a complex choice. In order to obtain optimal results, the following considerations are mandatory: thorough preoperative planning, a complete knowledge of the devices that are used, accurately performed surgery, and appropriate follow-up...

Background: Chest wall resection and reconstruction (CWRR) is quite challenging in surgery, due to evolution in techniques. Neoplasms of the chest wall, primary or secondary, have been considered inoperable for a long time. Thanks to evolving surgical techniques, reconstruction after extensive chest wall resection is possible with good functional and aesthetic results. Methods: In our single-center experience, seven cases of extensive CWRR for tumors were performed with a multidisciplinary approach by both thoracic and plastic surgeons...

Background: Nipple preservation provides superior aesthetic results as well as patient satisfaction in patients treated with both therapeutic and prophylactic mastectomy. Post-operative nipple ischemia and necrosis presents a unique clinical challenge that may be treated with hyperbaric oxygen therapy or conservative measures alone. To date, the efficacy of hyperbaric oxygen on post-operative nipple ischemia has yet to be evaluated. Methods: A retrospective review of patients treated with either hyperbaric oxygen or conservative management was performed...

The implant-prosthetic rehabilitation of edentulous upper jaws has always been complex for surgeons and dentists. The lack of bone in both vertical and horizontal dimension does not allow the correct insertion of dental implants. In addition, patients with edentulous upper and lower arch have a loss of vertical dimension of the face and an aged expression. Many surgical techniques have been proposed to increase the bone volume, height and thickness, such as the Le Fort I osteotomy, the bone grafts and the placement of dental implants...

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an uncommon neoplasia occurring in women with either cosmetic or reconstructive breast implants. The actual knowledge about BIA-ALCL deriving from the literature presents several limits, and it remains difficult to make inferences about BIA-ALCL epidemiology, cause, and pathogenesis. This is the reason why the authors decided to organize an evidence-based consensus conference during the Maurizio Bruno Nava (MBN 2016) Aesthetic Breast Meeting held in Milan in December of 2016...

BACKGROUND: Capsular contracture around breast implants is a severe and unpredictable complication experienced by up to 50 percent of patients after breast augmentation and reconstruction, and represents a major cause leading to reoperation. Several lines of evidence point to the involvement of subclinical infections and of bacterial biofilm formation. METHODS: To reduce the incidence of capsular contracture following mammaplasty, the authors studied the correlation between contamination by exogenous and endogenous bacterial flora and the capacity to develop bacterial biofilm in mammary implants...

BACKGROUND: The breast reconstructive subpectoral technique commonly leads to functional consequences. Recently, a new conservative prepectoral breast reconstruction (PPBR) technique was proposed and its surgical safety and aesthetic effectiveness proved. The aim of this prospective nonrandomized study was to compare the functional and economical outcomes of the PPBR procedure versus the subpectoral one. PATIENTS AND METHODS: From February 2015 to September 2016, 86 patients underwent mastectomy with immediate implant-based reconstruction...

BACKGROUND: Fixed prosthodontic treatment (crowns, fixed dental prostheses (FDPs), complete arch prostheses) involves the use of several different materials to replace missing tooth structure. Traditionally full metal or metal frameworks veneered with ceramic (metal-ceramic (MC)) have been used. In recent years several different metal-free systems have become available to clinicians and patients. In general, metal-free restorations should allow practitioners to better reproduce natural tooth colour, avoiding shortcomings of MC restorations...

INTRODUCTION: As well as the chin is an important esthetic unit of the facial structure, it is also the region having a key role in the appearance of the face. Correction of cosmetic and functional deformities that may occur in this region because of serious hypoplasia (microgenia) is performed by chin augmentation. Chin augmentation is most frequently performed via implant or osseous genioplasty in the literature. Both 2 techniques have their own advantages and disadvantages. In the literature, various studies comparing these 2 techniques and their long-term results are present, but in some severe microgenia cases, these techniques can be insufficient only for augmentation...

Silicone implants are widely used in aesthetic and reconstructive breast surgery. Silicone lymphadenopathy is a well-known rare complication of implant insertion. Silicone leakage from a rupture or silicone bleeding can accumulate in lymph nodes. Foreign body reactions in the affected lymph nodes may be misdiagnosed as metastasis or malignant lymphadeno pathy upon initial presentation if silicone lymphadenopathy is not considered in the initial diagnosis. We report a case of siliconoma with extensive involvement of multiple lymph nodes mimicking malignant features to emphasize that clinicians should carefully evaluate each patient's medical history and disease status during differential diagnosis...

Aesthetic implant restoration in the anterior maxilla is a challenge for clinicians. Alveolar ridge and surrounding gingiva deficiencies aggravates implant placement in the aesthetic area. This case report describes a technique for aesthetic single implant placement with simultaneous bone grafting and soft tissue thickening. At the time of implant surgery, allogenic (Maxgraft, Botiss Biomaterials, Germany) and xenogenic bone substitute (Cerabone, Botiss Biomaterials, Germany) was used for bone grafting, soft tissues were augmented simultaneously with collagen tissue matrix derivate membrane (Mucoderm, Botiss Biomaterials, Germany)...
