PURPOSE: To integrate extra-oral facial scanning information with CAD/CAM complete dentures to immediately rehabilitate terminal dentition. MATERIALS AND METHODS: Ten patients with terminal dentition scheduled for total extraction and immediate denture placement were recruited for this study. The patients were submitted to a facial scanning procedure using the in-office PritiMirror scanner with bite registration records in-situ. Definitive stone cast models and bite records were subsequently submitted to a lab scanning procedure using the lab scanner (iSeries DWOS; Dental Wings)...

The latissimus dorsi myocutaneous flap (LDMF) is a reliable and frequently used option to bring vascularized skin and soft tissue to improve the stability and aesthetic result in breast reconstruction. Standard techniques with skin paddle inset in a horizontal or oblique fashion preferentially improve anterior projection (when inset at the mastectomy scar) or lower pole and infra-mammary fold (IMF) constriction (when inset into the IMF). Here, we describe a modification for inset of the LDMF that improves both anterior projection and lower pole/IMF constriction, while also allowing the latissimus muscle to fan out and provide complete implant coverage...

BACKGROUND: Asian noses are relatively small and flat compared to Caucasians; therefore, rhinoplasty procedures often focus on dorsal augmentation and tip projection rather than reduction in the nasal framework. Various autologous and alloplastic implant materials have been used for dorsal augmentation. Recently, human acellular dermal matrices have been introduced as an implant material for dorsal augmentation, camouflaging autologous implants without an additional donor site. Here, we introduce a cross-linked human acellular dermal matrix as an implant material in augmentation rhinoplasty and share the clinical experiences...

Background: To report our experience of infections in deep brain stimulation (DBS) surgeries comparing shaving versus no shaving of cranial hair. Nonshaving is strongly preferred by patients due to aesthetic and psychological factors. Methods: This study is a prospective follow-up of the infection rate in 43 nonshaven DBS cases between April 2014 and December 2015 compared to our former infection rate with shaving in our center. Minimum follow-up was 6 months. All patients, except 7 epilepsy patients, received implantation of the electrodes together with the extension cables and internal pulse generator in one session...

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare peripheral T cell lymphoma. BIA-ALCL is a disease of the fibrous capsule surrounding the implant and occurs in patients after both breast reconstruction and augmentation. More than 300 cases have been reported so far, including two in a transgender patient. Here we describe BIA-ALCL presented with a mass in a transgender patient and the first case of BIA-ALCL in the Czech Republic. In 2007, a 33-year-old transgender male to female underwent bilateral breast augmentation as a part of his transformation to female...

The treatment of choice in cases of avulsed permanent teeth is the immediate reimplantation. However, this conduct does not always work favorably, either by failures in the initial approach or by inappropriate interventions. In this sense, the aim of this study is to present an alternative prosthetic rehabilitation with the use of orthodontic mini-implants in the anterior region. This case reports a ten-year-old child with history of avulsion of superior central incisors. The therapeutic approach was planned to promote physiological teeth contacts and acceptable esthetics and phonetics...

The aim of this qualitative study was to gain a deeper understanding of patient's perceptions of wearing implant retained overdentures with ball-shaped or cylindrical attachment systems. Twenty-two wearers of implant-supported overdentures participated in this qualitative study based on a randomized crossover clinical trial that aimed to compare a cylindrical attachment (Locator, Zest Anchors Inc, Escondido, CA, USA) and a ball attachment (Retentive Anchor, Straumann AG, Basel, Switzerland). In the phase I of the study, group A experienced ball attachments (n=11) and group B Locator attachment (n=11) for one year...

This article describes the use of implant-enhanced and total-autologous latissimus dorsi myocutaneous flaps in breast reconstruction. It addresses the indications for use of this reconstruction alternative, which have recently been expanded thanks to the advent of high-volume fat grafting. Given its straightforward dissection, reliable vascular pedicle, variety of approaches, and potential for excellent aesthetic results, use of latissimus dorsi flaps may be considered among first-line options in selected patients...

The authors document their experience in the use of synthetic 100% bioresorbable surgical mesh (TIGR Matrix, Novus Scientific, Uppsala, Sweden) in breast reconstruction as well as in breast aesthetic surgery. They performed a retrospective review on patients who underwent implant-based breast reconstruction as well as patients who underwent breast reduction mammoplasty procedures with the use of TIGR Matrix Surgical Mesh. When compared with other synthetic but nonresorbable meshes, it appears to show a potentially lower seroma and infection rates, but most importantly, a lower rate of revisional and mesh explantation surgeries...

Rehabilitation following ablative skull base surgery remains a challenging task, given the complexity of the anatomical region, despite the recent advances in reconstructive surgery. Remnant defects following resection of skull base tumors are often not amenable to primary closure. As such, numerous techniques have been described for reconstruction, including local rotational muscle flaps, pedicled flaps with skin paddle, or even free tissue transfer. However, not all patients are appropriate surgical candidates and therefore may instead benefit from nonsurgical options for functional and aesthetic restoration...

In aesthetic sites, the integrity of the facial bone wall dimension in the anterior maxilla is jeopardized by physiologic and structural changes postextraction. An effective regenerative protocol is key to reestablish and maintain the hard and soft tissue dimensions over time. The present prospective case series study examined the effectiveness of early implant placement with simultaneous contour augmentation through guided bone regeneration with a 2-layer composite graft in postextraction single-tooth sites over an observation period of 10 y among 20 patients...

The loss of superior midface contour and projection can be corrected with the use of injectable hyaluronic acid (HA) dermal fillers, however, the most frequently used injection pattern employs a technique which was originally designed for malar implant surgery. Here we describe a novel injection pattern for restoring facial contours with a HA dermal filler inspired by traditional make-up artistry, which includes greater superolateral positioning of injection sites. Importantly, this technique helps injectors avoid creating an excess of volume in the anterior portion of the malar complex...

The objective of this case report is to introduce a customized CAD/CAM freeze-dried bone allograft (FDBA) block for its use in Guided Bone Regeneration (GBR) procedures for severely deficient maxillary bones. Additionally, a special newly developed remote incision technique is presented to avoid wound dehiscence. The results show optimal integration behavior of the FDBA block after six months and the formation of new vital bone. Thus, the results of the present case report confirm the use of the customized CAD/CAM bone block for augmentation of complex defects in the maxillary aesthetic zone as a successful treatment concept...

REVIEW
John Y S Kim, Alexei S Mlodinow
Of the nearly 90,000 implant-based breast reconstructions performed in the United States, the majority use internal soft-tissue support. Aesthetically, these constructs may allow for better positioning of prosthesis, improve lower pole expansion, and increase projection. They may have particular utility in direct-to-implant, nipple-sparing mastectomies, and prepectoral reconstructions. In recent years, new permutations of acellular dermal matrices have evolved with diverse shapes, sizes, form-factor innovations, and processing characteristics...

REVIEW
Hina Panchal, Evan Matros
Postmastectomy immediate breast reconstruction in the U.S. continues to experience an upward trend owing to heightened awareness, innovations in reconstructive technique, growing evidence of improved patient-reported outcomes, and shifts in mastectomy patterns. Women with unilateral breast cancer are increasingly electing to undergo contralateral prophylactic mastectomy, instead of unilateral mastectomy or opting for breast conservation. The ascent in prophylactic surgeries correlates temporally to a shift toward prosthetic methods of reconstruction as the most common technique...

Generally, the main complications of silicone implantation are local symptoms. However, some patients develop late-onset systemic symptoms often associated with a rare form of hyperactive immune response, as part of a syndrome known as autoimmune syndrome induced by adjuvants (ASIA). Reported cases of ASIA have shown resolution with explantation, but not with immunomodulatory therapy. In this report, we described a case of a previously healthy 23-year-old woman, who has undergone silicone breast implant augmentation, for aesthetic reasons, and developed localized cutaneous impairment 3 years postsurgery...

Tooth replacement in the anterior maxilla is most often indicated after traumatic dental injury or due to congenital missing teeth. Treatment alternatives include implant-supported restorations, conventional fixed bridges, acid-etched bridges, orthodontic space closure, or autotransplantation. Dental implants have gained increased popularity over the last 40 years. However, this treatment modality is contraindicated in patients with continuous growth of the alveolar process due to the risk of severe infrapostion of the dental implant...
