Diverse clinical advancements, together with some relevant technical innovations, have led to an increase in popularity of tunneling flap procedures in plastic periodontal and implant surgery in the recent past. This trend is further promoted by the fact that these techniques have lately been introduced to a considerably expanded range of indications. While originally described for the treatment of gingival recession-type defects, tunneling flap procedures may now be applied successfully in a variety of clinical situations in which augmentation of the soft tissues is indicated in the esthetic zone...

In contemporary reconstructive periodontal and implant surgery, attaining uncomplicated wound healing in the early postoperative healing phase is the key to achieving a successful treatment outcome and is of central interest, from the clinical as well as the scientific perspective. The realization of primary wound healing is the central challenge in most cases. Two of the evidence-based factors that affect postoperative wound healing can be influenced by the surgeon: the blood supply to the surgical site and postoperative wound stability...

OBJECTIVES: Implant placement immediately after tooth extraction is often accompanied by resorption of surrounding tissues. A clinical technique was developed where the buccal portion of the root is retained to preserve the periodontal ligament and bundle bone. This technique is based on animal studies showing the potential to preserve the facial tissues utilizing this approach. The purpose of this study was to gain more insight regarding the safety of the technique with regard to biological and implant-related long-term complications and to observe the clinical appearance of the peri-implant tissues...

BACKGROUND: Despite evidence that enrollment with hospice services has the potential to reduce hospital readmission rates, previous research has not examined exactly how hospitals may promote the appropriate use of hospice and palliative care for their discharged patients. Therefore, we sought to explore the strategies used by hospitals to increase the use of hospice and palliative care for patients at risk of readmission. METHODS: We conducted a secondary analysis of qualitative data from a study of hospitals that were participating in the State Action on Avoidable Readmissions (STAAR) initiative, a quality improvement collaborative...

OBJECTIVES: Despite increased hospice use over the last decade, end-of-life care intensity continues to increase. To understand this puzzle, we sought to examine regional variation in intensive end-of-life care and determine its associations with hospice use patterns. METHODS: Using Medicare claims for decedents aged 66 years and above in 2011, we assessed end-of-life care intensity in the last 6 months of life across hospital referral regions (HRRs) as measured by proportion of decedents per HRR experiencing hospitalization, emergency department use, intensive care unit (ICU) admission, and number of days spent in hospital (hospital-days) and ICU (ICU-days)...

Anterior teeth are often affected by accidental dental trauma and may eventually be lost. When the neighboring teeth are unharmed, implant-supported crowns are often the preferred treatment choice. When not only the teeth but also the supporting hard and soft tissue has been lost, surgical reconstruction may be needed. However, in combined horizontal and vertical class III defects, the available augmentation techniques are often not predictable. In this case report, two neighboring mandibular central incisors were replaced by two implants after soft and hard tissue augmentation with the cortical bone plate method...

BACKGROUND: Little is known about state-level variation in patterns of hospice use, an important indicator of quality of care at the end of life. Findings may identify states where targeted efforts for improving end-of-life care may be warranted. OBJECTIVE: Our aim was to characterize the state-level variation in patterns of hospice use among decedents and to examine state, county, and individual factors associated with these patterns. METHODS: We conducted a retrospective analysis of Medicare fee-for-service decedents...

Soft tissue replacement grafts have become a substantial element to increase tissue volume in plastic periodontal and implant surgery. Autogenous subepithelial connective tissue grafts are increasingly applied in aesthetic indications like soft tissue thickening, recession treatment, ridge preservation, soft tissue ridge augmentation and papilla re-construction. For the clinical performance of connective tissue graft harvesting and transplantation, a fundamental understanding of the anatomy at the donor sites and a sound knowledge of tissue integration and re-vascularization processes are required...

BACKGROUND: The "socket-shield technique" has shown its potential in preserving buccal tissues. However, front teeth often have to be extracted due to vertical fractures in buccolingual direction. It has not yet been investigated if the socket-shield technique can only be used with intact roots or also works with a modified shield design referring to vertical fracture lines. PURPOSE: The aim of this study was to assess histologically, clinically, and volumetrically the effect of separating the remaining buccal root segment in two pieces before immediate implant placement...
