- Objectives: The aim of the ITI Consensus Workshop on zygomatic implants was to provide Consensus Statements and Clinical Recommendations for the use of zygomatic implants.Materials and methods: Three systematic reviews and one narrative review were written to address focused questions on (1) the indications for the use of zygomatic implants; (2) the survival rates and complications associated with surgery in zygomatic implant placement; (3) long-term survival rates of zygomatic implants and (4) the biomechanical principles involved when zygoma implants are placed under functional loads. Based on the reviews, three working groups then developed Consensus Statements and Clinical Recommendations. These were discussed in a plenary and finalized in Delphi rounds.Results: A total of 21 Consensus Statements were developed from the systematic reviews. Additionally, the group developed 17 Clinical Recommendations based on the Consensus Statements and the combined expertise of the participants.Conclusions: Zygomatic implants are mainly indicated in cases with maxillary bone atrophy or deficiency. Long-term mean zygomatic implant survival was 96.2% [95% CI 93.8; 97.7] over a mean follow-up of 75.4 months (6.3 years) with a follow-up range of 36-141.6 months (3-11.8 years). Immediate loading showed a statistically significant increase in survival over delayed loading. Sinusitis presented with a total prevalence of 14.2% [95% CI 8.8; 22.0] over a mean 65.4 months follow-up, representing the most common complication which may lead to zygomatic implant loss. The international experts suggested clinical recommendations regarding planning, surgery, restoration, outcomes, and the patient's perspective.

- BACKGROUND: The long-term success rates achieved in dental implantology suggest that flexibility might well exist within the various implant systems to a degree that an altered protocol (ie, one-stage surgery and immediate or early loading) can be performed under controlled conditions. However, before variations of the protocol can be considered for general use, they must be subjected to critical analysis, particularly with respect to the predictability of osseointegration, alteration of soft tissue barrier, and relative change in bone height around the implants. PURPOSE: The aim of this prospective multicenter study was to evaluate implant survival and periimplant conditions around endosseous implants placed in a one-stage surgical procedure and early loading. MATERIALS AND METHODS: A total of 170 implants were placed in 40 patients with mandibular edentulism and were functionally loaded within 6 weeks with overdentures (n = 30) or fixed prostheses (n = 10). All patients and prosthetic constructions were evaluated according to a standardized protocol during 3 years of follow-up. Cumulative implant survival rates were calculated, and implant loss in relation to implant size and bone quality and quantity were evaluated. Furthermore, the protocol included assessment of clinical (plaque and bleeding scores, prosthesis stability) and radiographic parameters. RESULTS: Over a period of 3 years, the implant survival rate was 93% for both implants and prostheses (fixed or removable). No implants were lost after the first year of loading. The periimplant tissues were in a healthy condition. Mean marginal bone resorption from the time of loading to the 3-year follow-up was 0.41 mm (SD 0.52). CONCLUSIONS: From this study it may be concluded that early loading results in good implant survival and proper periimplant health in edentulous mandibles.

Peri-Implant Endosseous Healing Properties of Dual Acid-Etched Mini-Implants with a Nanometer-Sized Deposition of CaP : A Histological and Histomorphometric Human Study

- PURPOSE: The aim of this histological and histomorphometric study was to compare the early peri-implant endosseous healing properties of a dual acid-etched (DAE) surface (Osseotite, Implant Innovations Inc., Palm Beach Gardens, FL, USA) with a DAE surface modified with nanometer-sized calcium phosphate (CaP) particles (NanoTite, Implant Innovations Inc.) in grafted and mature maxillary bone. MATERIALS AND METHODS: Fifteen patients received two mini-implants, 1 with DAE surface (control) and 1 with a DAE + CaP surface (test), to fixate an iliac crest bone graft to the maxilla. A part of each mini-implant was in contact with the grafted bone and a part extended into the native maxillary bone. After a healing period of 3 months, the specimens were harvested and analyzed. RESULTS: Overall, a trend was seen for stronger bone response around the test mini-implants in the native bone of the maxilla. However, only the old bone particles measured by percentages of bone-to-implant contact and bone area were statistically significant (p = .025 and p = .042, respectively). CONCLUSIONS: The NanoTite surface increases the peri-implant endosseous healing properties in the native bone of the maxilla compared with the Osseotite surface, while this difference was not visible in the bone graft area. This might be a result of the lower remodeling process of the graft.

Preprosthetic surgery : narrative review and current debate

Tidskriftsartikel (refereegranskat)abstract
- This review describes the role of modern preprosthetic surgery. The atrophic edentulousjaw can cause severe functional impairment for patients, leading to inadequate denture retention,reduced quality of life, and significant health problems. The aim of preprosthetic surgery is to restorefunction and form due to tooth loss arising from congenital deformity, trauma, or ablative surgery.Alveolar bone loss is due to disuse atrophy following tooth loss. The advent of dental implants andtheir ability to preserve bone heralded the modern version of preprosthetic surgery. Their ability tomimic natural teeth has overcome the age-old problem of edentulism and consequent jaw atrophy.Controversies with preprosthetic surgery are discussed: soft tissue versus hard tissue augmentationin the aesthetic zone, bone regeneration versus prosthetic tissue replacement in the anterior maxilla,sinus floor augmentation versus short implants in the posterior maxilla—interpositional bone graftingversus onlay grafts for vertical bone augmentation. Best results for rehabilitation are achieved bythe team approach of surgeons, maxillofacial prosthodontists/general dentists, and importantly,informing patients about the available preprosthetic surgical options.

- Objectives: The task of working Group 2 at the 6th Consensus Meeting of the European Association for Osseointegration was to comprehensively assess the effects of soft tissue augmentation procedures at dental implant sites on clinical, radiographic and patient-reported outcome measures (PROMs) including an overview on available outcome measures and methods of assessment.Materials and methods: Three systematic reviews and one critical review were performed in advance on (i) the effects of soft tissue augmentation procedures on clinical, radiographic and aesthetic outcomes, (ii) reliability and validity of outcome measures and methods of assessment and (iii) PROMs applied in clinical studies for soft tissue augmentation procedures at dental implant sites. Major findings, consensus statements, clinical recommendations and implications for future research were discussed in the group and approved during the plenary sessions.Results: The four reviews predominantly revealed: Soft tissue augmentation procedures in conjunction with immediate and delayed implant placement result in superior aesthetic outcomes compared to no soft tissue augmentation in the zone of aesthetic priority. Soft tissue augmentation procedures have a limited effect on marginal bone level changes compared to implant sites without soft tissue augmentation. Clinically relevant parameters (gingival index, mucosal recession) and plaque control improve at implant sites when the width of keratinised mucosa is increased. A variety of aesthetic indices have been described with good reliability. Pink Esthetic Score and Complex Esthetic Index are the most validated aesthetic indices for single implants, though. Superimposed digital surface scans are most accurate to assess profilometric tissue changes. PROMs following soft tissue augmentation procedures have been assessed using various forms of questionnaires. Soft tissue augmentation had a limited effect on PROMs.Conclusions: Soft tissue augmentation procedures are widely applied in conjunction with implant therapy. Depending on the indication of these interventions, clinical, radiographic and aesthetic outcomes may improve, whereas the effect on PROMs is limited.
