Introduction: Peri-implantitis is an inflammation of the soft and hard tissues surrounding an implant that results in the destruction of alveolar bone. Surgical flaps are usually elevated to allow for thorough debridement and disinfection of the implant surface. This frequently results in gingival recession, crown margin exposure, and a poor esthetic result. This is not desirable in the esthetic zone. In this case report, a minimally invasive flapless technique incorporating the use of curettage and antiseptics is used to successfully disinfect a contaminated dental implant to allow for soft tissue readherence and pocket reduction. Radiographic bone fill is also seen. The results have been maintained for 2 years.
Case Presentation: A 54-year-old female patient presented with peri-implantitis, characterized by episodic pain and suppuration from a buccal fistula on an implant replacing tooth #10. The implant was placed and provisionally restored 10 years previously. It showed radiographic bone loss to the fifth thread, but it was non-mobile. Treatment consisted of removal of the temporary crown and abutment, which provided access for the surgical curettage of the granulomatous tissue and for the mechanical debridement of the implant surface with a titanium curet. Chemical detoxification of the implant surface, as well as the abutment, screw, and screw hole, was achieved with the use of sterile saline and a 0.25% sodium hypochlorite solution. Antibiotics were also prescribed. At a 2-year follow-up, probing depths were reduced to <4 mm, and there was radiographic bone fill.
Conclusions: A minimally invasive flapless technique incorporating surgical curettage debridement of the inflamed soft tissue and chemical detoxification with antiseptics can be a viable alternative for the treatment of anterior implants with peri-implantitis, especially when the patient has a high smile line. Successful and effective debridement and disinfection of a previously contaminated implant surface can be achieved without reflecting a flap.

Background: Assessing the endothelialization of occlusive devices noninvasively remains a challenge. Cardiac computed tomography angiography (CTA) can be employed to evaluate device endothelialization based on contrast uptake within the occluder.
Objective: This study examined device endothelialization using cardiac CTA and investigated the pathological associations.

Periodontitis, a widespread inflammatory disease, is the major cause of tooth loss in adults. While mechanical periodontal therapy benefits the periodontal disease treatment, adjunctive periodontal therapy is also necessary. Topically applied anti-inflammatory agents have gained considerable attention in periodontitis therapy.

An implantable ventricular assist device became smaller and has been used for small body size patients. However, it is still challenging to determine whether it is implantable for pediatric patients. The preoperative computed tomography virtual simulation provided spatial information among the pump, intracardiac structures, and extracardiac structures, which was very useful to assess the implantability for borderline children.

Electrographic recording of brain activity through either surface electrodes (electroencephalography, EEG) or implanted electrodes (electrocorticography, ECOG) are valuable research tools in neuroscience across many disciplines, including epilepsy, sleep science and more. Research techniques to perform recordings in rodents are wide-ranging and often require custom parts that may not be readily available. Moreover, the information required to connect individual components is often limited and can therefore be challenging to implement.

Regenerating periodontal bone defect surrounding periodontal tissue is crucial for orthodontic or dental implant treatment. The declined osteogenic ability of periodontal ligament stem cells (PDLSCs) induced by inflammation stimulus contributes to reduced capacity to regenerate periodontal bone, which brings about a huge challenge for treating periodontitis. Here, inspired by the adhesive property of mussels, we have created adhesive and mineralized hydrogel microspheres loaded with traditional compound cordycepin (MMS-CY).
