This case series investigated the effect of a combination therapy utilizing connective tissue graft (CTG) in the treatment of periodontal regeneration of mandibular Class III/IV furcation involvement (FI). Six patients diagnosed with periodontitis stage III or IV (grade A to C), presenting with Class III or IV FI, were treated with fibroblast growth factor-2 and carbonate apatite in combination with CTG. The following clinical parameters were evaluated at baseline and after 6, 12, and 18 months: periodontal probing depth, clinical attachment level, furcation invasion, radiographic vertical defect depth, and gingival phenotype. Significant improvements in clinical parameters were observed in all treated FI sites. Four Class III defects and one Class IV defect obtained complete closure, and one Class IV defect was improved to Class I. This case series showed the potential of administering combination regenerative therapy for changing the prognosis of hopeless teeth with severe furcation defects.
Surgical treatment of infrabony defects may result in gingival recession of the neighboring teeth. The aim of this clinical report is to describe a surgical technique to promote gingival margin stability in the treatment of infrabony defects at sites with a thin or medium gingival phenotype. A coronally advanced entire papilla preservation (CA-EPP) flap with a connective tissue graft (CTG) was executed in two different clinical cases. This technique substantially improved interproximal clinical attachment level and pocket closure, with no gingival recession. A CA-EPP flap using a CTG may promote gingival margin stability and can be recommended in regenerative periodontal procedures.

Case presentation: Midfacial peri-implant soft tissue recession poses a significant challenge to achieving satisfactory aesthetic outcomes and requires a comprehensive, multidisciplinary approach. The present study describes two challenging cases in which implants were aesthetically compromised. A predictable technique was employed to manage these cases by using the implant itself as a tent to achieve 3D horizontal and vertical soft tissue building, which resulted in improved patient satisfaction. The first case involved a deep, severely buccally placed implant situated adjacent to compromised tooth structure. Horizontal and vertical soft tissue augmentation were carried out using a healing abutment to maintain the connective tissue coronal to the implant. The final fixed prosthesis was then delivered on top of the permanent submerged implant, with excellent soft tissue outcomes and a high level of patient satisfaction. The second case involved two compromised, deep, buccally placed implants that were managed by performing a permanent implant submergence technique on the maxillary left central incisor implant and augmenting the soft tissue vertically and horizontally. The final fixed prosthesis was delivered between the maxillary left lateral incisor implant and the previously prepared maxillary right central incisor, resulting in an acceptable aesthetic outcome. The technique presented managed the peri-implant soft tissue dehiscence effectively and restored the previously deficient peri-implant papillae.
Conclusions: The key to treating challenging aesthetic complications encountered with implants is presurgical prosthetic preparation followed by use of a comprehensive surgical technique to optimise soft tissue thickness and height and address compromised aesthetics in a single surgical step. Use of a permanent implant submergence technique with remediation of associated defects may be a viable clinical approach that is not often explored for these types of defects.

The aim of the present study was to evaluate, clinically and via CBCT, the long-term efficacy of a bioresorbable polylactic acid membrane combined with deproteinized bovine bone graft (DBBM) and compare it to enamel matrix derivative (EMD) combined with DBBM graft in the treatment of class II furcation defects. Sites were randomly assigned to the test group (Guidor Matrix Barrier + Bio-Oss) or the control group (Emdogain + Bio-Oss). Probing pocket depth (PPD), clinical attachment level (CAL), gingival recession (REC), and keratinized tissue (KT) width were assessed at 12 and 24 months, and radiographic bone gain was investigated at 24 months via CBCT. Both groups showed a significant radiographic bone fill and clinical gain. The combination of Emdogain + Bio-Oss showed better clinical outcomes and less complications, though this difference was not statistically significant.
The present study introduces a novel "anatomic recession ratio" (ARR) and evaluates the clinical outcomes of using a tunnel technique (TUN) with a connective tissue graft (CTG) for root coverage (RC). Sixteen systemically healthy patients contributing a total of 33 recession types 1 and 2 were treated with TUN + CTG. The predictive value of a panel of baseline clinical parameters (ARR) on RC was evaluated 12 months postoperatively. At 12 months, mean recession depth decreased from 2.74 ± 0.22 mm to 0.46 ± 0.13 mm (P < .0001); 19 sites (58%) showed complete RC, and the mean RC rate was 88.85% ± 2.73%. The mean ARR value was 0.74 ± 0.3, revealing a positive correlation with RC (r2: 0.73, P < .0001). The 12-month esthetic evaluation resulted in a score of 8.52 ± 1.75 using the root coverage esthetic score. TUN + CTG is effective in reducing recession depth and obtaining good esthetic outcomes. Within the limits of the present study, it may be suggested that ARR has potential as an analytical baseline parameter for RC outcomes with TUN + CTG.
The aim of the present study was to generate an international and multidisciplinary consensus on the clinical management of implant protrusion into the maxillary sinuses and nasal fossae. A total of 31 experts participated, 23 of whom were experts in implantology (periodontologists, maxillofacial surgeons and implantologists), 6 were otolaryngologists and 2 were radiologists. All the participants were informed of the current scientific knowledge on the topic based on a systematic search of the literature. A list of statements was created and divided into three surveys: one for all participants, one for implant providers and radiologists and one for otolaryngologists and radiologists. A consensus was reached on 15 out of 17 statements. According to the participants, osseointegrated implants protruding radiographically into the maxillary sinus or nasal fossae require as much monitoring and maintenance as implants fully covered by bone. In the event of symptoms of sinusitis, collaboration between implant providers and otolaryngologists is required. Implant removal should be considered only after pharmacological and surgical management of sinusitis have failed.

Kariesläsionen mit tiefen Rändern sind in der zahnärztlichen Praxis erhebliche Herausforderungen. Folgende Schlüsselaspekte dieses Problems werden im vorliegenden Beitrag diskutiert: Wie ist unter restaurativem Gesichtspunkt mit einem tiefen Kavitätenrand umzugehen? Wann und wie sollte chirurgisch interveniert werden? Welcher ist der beste Zeitpunkt für die definitive restaurative Versorgung nach einer chirurgischen Intervention? Die mittlerweile verfügbaren Restaurationsmaterialien und Adhäsivtechniken ermöglichen minimalinvasive Behandlungsansätze und damit einen umfangreichen Substanzerhalt und helfen dabei, unerwünschte Reaktionen der parodontalen Gewebe zu vermeiden. Je nach klinischer Ausgangslage kommen bei subgingivalen Kavitätenrändern drei Behandlungsoptionen in Betracht. Liegt der Rand maximal 1,5 mm unter dem Gingivarand, ist eine Anhebung des Kavitätenrands unter Kofferdam möglich, was eine optimale Restauration und Weichgewebeintegration erlaubt. Liegt der Kavitätenrand mehr als 1,5 mm unter dem Gingivarand, ist vor der Restauration eine chirurgische Intervention erforderlich. Liegt der Rand noch mindestens 2 mm über dem Knochen, wird ein ästhetisches suprakrestales Gewebemanagement (Supracrestal Tissue Esthetic Management, STEM) durchgeführt. Das heißt, es genügt eine Osteoplastik, um das suprakrestale Attachment neu zu etablieren und die restaurative Behandlung durchführen zu können. Eine Ostektomie ist nicht nötig. Liegt der Kavitätenrand weniger als 2 mm koronal zum Knochenkamm, ist eine Kronenverlängerung mit einer minimalen Ostektomie und anschließenden Osteoplastik indiziert.
Carious lesions with deep margins represent a challenge in daily clinical practice. The following key points are discussed in this article: how to manage a deep margin from a restorative point of view; when and how to perform a surgical procedure; and when it is favorable to carry out definitive restoration work after surgery. The restorative materials and adhesive procedures available today allow minimally invasive techniques to be used on dental tissue with a high preservation of tooth structure. These materials and techniques help to avoid adverse periodontal tissue reactions. Depending on the clinical situation, three treatment options are available when dealing with a subgingival margin. If the depth of the cavity margin is at a maximum distance of 1.5 mm below the gingival margin, isolation with rubber dam allows the performance of interproximal margin relocation, thereby facilitating optimal restoration and periodontal tissue integration. If the margin is located deeper than 1.5 mm below the gingival margin, surgery is necessary before any restorative work can take place. When the margin is within 2 mm above the bone crest, a supracrestal tissue esthetic management (STEM) procedure is undertaken, which means that no ostectomy is required and only osteoplasty is necessary to reshape the preexisting supracrestal attachment, thereby allowing the restorative work to proceed. When the margin is less than 2 mm above the bone crest, crown lengthening with minimal ostectomy and subsequent osteoplasty becomes necessary.
The gingival thickness (GT) and keratinized tissue width (KTW) constitute the gingival phenotype, a concept that has received a great deal of appreciation in recent years. Gingival phenotype modification has been achieved via different surgical techniques and grafting materials. Despite the superiority of autogenous grafts, their increased patient morbidity and limited recourse has led to the development of graft substitutes. The human dermal matrix is a notable example that, depending on its processing method, can become freeze-dried or solvent-dehydrated acellular dermal matrix (FDADM and SDADM, respectively). This article reports the 9-year outcomes of a randomized clinical trial regarding gingival phenotype modification following root coverage with FDADM and SDADM. Twelve of the original 20 patients were available at the 9-year follow-up. Overall, the outcomes of gingival phenotype modification were maintained in both groups and at all sites after 9 years. For KTW, an incremental increase was observed over time in both groups, and minimal or no changes were noted in GT from the 1-year recall to the 9-year recall. However, the gingival margin level showed an apical shift for both groups.
The present prospective case series evaluated the efficacy, the intra- and postsurgical complications, and the patient-related outcomes of a tunnel technique with a subperiosteal bag (TTSB) for horizontal ridge augmentation prior to implant placement. Twenty-five systemically healthy patients searching for implant rehabilitation and presenting with a horizontal ridge deficiency requiring bone augmentation before implant placement were included. Guided bone regeneration (GBR) was performed using the TTSB technique, involving the preparation of a collagen membrane that is perforated, folded, and sutured to form a bag that is then filled with a xenogeneic bone graft material. The bag is then inserted into a subperiosteal tunnel. Horizontal bone gain (HBG) was calculated 6 months after the surgery using CBCT. Healing was uneventful and with minimal morbidity. Average HBG was 3.7 ± 1.8 mm (P < .05), with a vertical component gain of 1.3 ± 1.7 mm (P > .05). In 12 patients, additional bone augmentation was required at the time of implant placement. A higher HBG was achieved in the maxilla than in the mandible (4.3 ± 1.3 mm vs 3.2 ± 1.8 mm, respectively; P < .05), and sites with an initial horizontal ridge width ≤ 3.5 mm were associated with a higher chance of requiring additional bone grafting at the time of implant placement compared to sites with an initial horizontal ridge width > 3.5 mm. The present case series demonstrated that TTSB is an effective approach for ridge augmentation prior to implant placement with minimal intra- and postoperative complications or patient morbidity.
