Tooth-Implant Connection: A Review

The aim of this review was to assess the long-term outcomes of restorations supported by implants and natural teeth with regard to complications associated with implants, teeth, and restorations, as well as the influence on these parameters of the connector type used. A net-based search in PubMed was combined with a manual search. Clinical studies, reviews, and biomechanical studies were included. Information on survival rate, complication rate, incidence of tooth intrusion, and, where applicable, type of connector used, was retrieved from the clinical studies. Force distribution and types of connectors used were retrieved from the biomechanical study. A summary of outcomes was retrieved from the reviews. A total of 25 articles were selected for inclusion in this review, including clinical studies (15), biomechanical studies (7), and reviews (3). Implant success rates ranged from 79.5%–100%. Tooth complications occurred in 5.4%–11.8% of cases. Complications in the suprastructure were observed in 5%–90% of cases. Tooth intrusion presented in a total of 0%–66% of all cases, more often in cases with nonrigid connection (0%–66%) than in cases with rigid connection (0%–44%). Biomechanical studies show a large difference in stress distribution and in dependence on the type of connector used, with most studies demonstrating that nonrigid connectors drastically reduce stress on the suprastructure while increasing forces on supporting teeth and implants. Long-term success rates for tooth-implant connections are lower than for solely implant-supported restorations with regard to prognosis for teeth, implants, and suprastructure. Use of rigid connectors leads to more favorable clinical outcomes in terms of long-term stability, occurrence of complications, and tooth intrusion.

Introduction: The purpose of the current study was to investigate the periprocedural and long-term outcomes of stent implantation for de novo subclavian artery (SCA) disease. Material and Methods: We retrospectively investigated consecutive patients with de novo SCA lesions undergoing elective endovascular therapy procedures at our center between April 2004 and September 2015. All patients were included in the analyses of periprocedural outcomes, including procedural and clinical success. Subsequently, patients who completed the clinical follow-up and were assessed with brachial systolic pressure differences between the diseased and the contralateral arms, or angiographic stenosis, after stent implantation with procedural success were included in the analyses of long-term outcomes, including primary patency. Results: There were 62 patients (median 71.0 years, interquartile range 65.3-76.0 years; 45 men) with 62 de novo SCA lesions included in the analyses of periprocedural outcomes. There were 46 stenoses (74.2%) and 16 occlusions (25.8%). Our results indicated high procedural success rates for overall (95.2%), stenotic (97.8%), and occlusive (87.5%) lesions. Similarly, high clinical success rates were observed for overall (91.9%), stenotic (93.5%), and occlusive (87.5%) lesions. The median follow-up time was 6.0 years (interquartile range, 2.6-8.3 years). There were 48 patients with 48 de novo SCA lesions included in the analyses of long-term outcomes. Primary patency estimates were 97.7% (1 year), 97.7% (3 years), 93.1% (5 years), and 87.6% (7 years). Also, we observed a high estimate for freedom from reintervention for the target vessel (93.8%). Conclusion: Stent implantation for de novo SCA disease can be performed successfully and safely with favorable periprocedural and long-term outcomes.

Dental implants in partially edentulous patients are a predictable therapeutic option. In patients with reduced bone volume, tooth-to-implant connected prostheses have been described as a treatment option. In this systematic review, the incidence of biologic and technical complications and the long-term survival rates of tooth-implant supported fixed partial dentures (FPDs) are analyzed. In cases where a natural tooth is connected with an implant to support a FPD, a rigid connection should be preferred.

Abstract Background: To investigate the aetiopathology of recurrent epiphora or stickiness after dacryocystorhinostomy (DCR) surgery, identifiable on dacryocystography (DCG), and to assess the success rates of secondary corrective surgeries.Methods: Consecutive post-DCR DCG images from patients with recurrent symptoms were reviewed between 2012-2015.Results: 159 eyes of 137 patients were evaluated. 58 DCGs showed normal postoperative findings, 4 an upper/lower canalicular block, 13 a common canalicular block, 31 a completely closed anastomosis, 50 a narrow anastomosis, and 3 an anastomosis draining into a nasal sinus.The most successful corrective procedures for each failure category were: Lester Jones Tube (LJT) for a normal post-operative DCG (17/18 success), Sisler trephination with tubes for upper/lower canalicular block (1/2 success), redo-DCR with tube for common canalicular blockage (5/6 success), redo-DCR +/- tube for completely closed anastomosis (12/16 success), LJT followed by redo-DCR +/- tube for narrow surgical anastomosis (1/1 and 17/27 success respectively), and redo-external-DCR with tube for anastomosis into a nasal sinus (1/1 success). Redo-DCR was ineffective in patients who had good post-DCR anatomical patency (22% success).Conclusion: This is the first study to report success rates of redo-DCR surgery according to anatomical findings confirmed by DCG. The outcome flow diagram help clinicians recommend procedures that are most likely to be successful for their patient’s specific anatomical abnormality. It also provides a visual tool for the shared decision-making process. Notably, symptomatic patients with a normal DCG post DCR are unlikely to benefit from redo-DCR, with a LJT being the recommended next step.

AbstractKnee dislocations (KDs) are devastating injuries for patients and present complex challenges for orthopaedic surgeons. Although short-term outcomes have been studied, there are few long-term outcomes of these injuries available in the literature. The purpose of this study is to determine factors that influence mid- to long-term clinical outcomes following surgical treatment of KD. A review of the current literature was performed by searching PubMed, the Cochrane Library, and Embase to identify clinical studies published from 2010 to 2019 with a minimum 2-year follow-up that reported outcomes following surgical treatment of KDs. Ten studies (6 level III, 4 level IV) were included. At mid- (2–10 y) to long-term (>10 y) follow-up, concomitant arterial, cartilage, and combined meniscus damage were predictive factors for inferior Lysholm and International Knee Documentation Committee (IKDC) scores when compared with patients without these associated injuries. Although concomitant neurological damage may influence short-term outcomes due to decreased mobility, at longer follow-up periods it does not appear to predict worse clinical outcomes when compared with patients without concomitant neurological injury. Frank and polytrauma KDs have been associated with worse mid- to long-term outcomes when compared with transient and isolated KDs. Patients who underwent surgery within 6 weeks of trauma experienced better long-term outcomes than those who underwent surgery longer than 6 weeks after the initial injury. However, the small sample size of this study makes it difficult to make valid recommendations. Lastly, female sex, patients older than 30 years at the time of injury and a body mass index (BMI) greater than 35 kg/m2 are factors that have been associated with worse mid- to long-term Lysholm and IKDC scores. The results of this review suggest that female sex, age >30 years, BMI >35 kg/m2, concomitant cartilage damage, combined medial and lateral meniscal damage, KDs that do not spontaneously relocate, and KDs associated with polytrauma may predict worse results at mid- to long-term follow-up.

The aim of this study was to assess the long-term clinical behavior of straight implants in comparison with intentionally tilted dental implants (ITDI) supporting fixed restorations in partial or total edentulous arches, analyzing implant survival and success rates, complications, and marginal bone loss (MBL) after >5 years of function. An electronic search was conducted in five electronic databases (MEDLINE/Pubmed, Embase, Web of Science, Scopus, and Cochrane Central Register of Controlled Trials) supplemented by a manual search. The electronic and manual search identified 1853 articles, of which 8 articles were selected for analysis. Out of a total of 3987 dental implants, 2036 were axial dental implants and 1951 tilted. Similar results were found in implant survival or overall implant success rates. Moreover, no statistically significant differences were found in MBL (p = 0.369; MD 0.116 mm (−0.137; 0.369) 95% CI) The prosthodontic/biological complications reported in the articles were very diverse and irregularly distributed. This systematic review suggests that there is no difference between tilted compared with straight dental implants in the medium-long term (>5 years). However, further research is needed to generate long-term data and confirm the present review’s findings.

The Impact

Objectives Vascular calcification is a well-known phenomenon and affects coronary and carotid arteries as well as other arterial beds. Presence of arterial calcification is associated with major adverse events in patients undergoing percutaneous coronary artery or carotid artery intervention. Even though there is a clear association between worse outcome and coronary-carotid calcification, there is no research that interrogated the relationship between iliac arterial calcification and clinical outcomes because of lack of data. Therefore, in this study, we aimed to investigate the impact of iliac arterial calcification on procedure success rates and long-term outcomes among patients undergoing endovascular intervention. Methods The records of 453 consecutive patients who underwent endovascular intervention due to symptomatic peripheral artery disease were analyzed. Patients were divided into two groups based on the presence or absence of heavy calcification of iliac arteries. For each group, technical aspects of procedures and subsequent clinical outcomes were analyzed. Results According to our study, the rate of restenosis following endovascular intervention at 6 and 12 months were similar between two groups. On the other hand, long-term restenosis was significantly higher in patients with heavy calcification of iliac arteries as compared to patients with low calcification on iliac arteries (32.2% vs. 12.8%, p < 0.05). Conclusions Our data showed that there was a strong association between heavy calcification of iliac arteries and long-term restenosis in patients undergoing endovascular intervention.

Abstract Purpose To evaluate the outcomes of initial trabeculectomy in granulomatous and non-granulomatous uveitis. Methods Retrospective comparative study of 68 eyes that underwent an initial trabeculectomy. Results The mean follow-up was 74.18 and 74.86 months in both groups (p = 0.95). The intraocular pressure decreased from 40.03 mmHg (± 7.2) and 36.48 mmHg (± 11.3) to 14.00 mmHg (± 6.2) and 13.48 mmHg (± 5.7), the number of medications decreased from 3.73 (± 0.7) and 3.58 (± 0.9) to 1.00 (± 1.4) and 1.13 (± 1.4) on the last follow-up (p < 0.01) in the granulomatous and non-granulomatous groups, respectively. More eyes in the granulomatous uveitis group developed delayed postoperative complications like cataract, transient hypotony and glaucoma progression. Success rates were 64.9 and 71.0%, while failure rates were 35.1 and 29.0% in both groups (p = 0.84). Conclusions Trabeculectomy seems to have comparable IOP control and survival in granulomatous and non-granulomatous uveitis. Nevertheless, more eyes in the granulomatous uveitis group developed late onset complications.

The IPS e.max system by Ivoclar Vivadent, offering a variety of products and indications, is widely used for all-ceramic restorations. We analyzed the clinical track record of these products in daily clinical practice, associating their restorative survival rate with various parameters to define recommendations for long-term stability. A total of 1058 full-coverage crowns and fixed partial dentures (FPDs) were evaluated retrospectively over up to 66.48 (37.05 ± 18.4) months. All were made of IPS e.max Press, IPS e.max CAD, IPS e.max Ceram or IPS e.max ZirPress and had been delivered by a private dental practice within three years. Uses not recommended by the manufacturer were also deliberately included. The five-year cumulative survival was 94.22% (i.e., 94.69% or 90.58% for glass-ceramic crowns or FDPs and 100% or 90.06% for zirconia-based crowns or FDPs). Significantly superior outcomes emerged for conventional vs. adhesive cementation and for vital vs. non-vital abutment teeth, but not for recommended vs. non-recommended uses. Caution is required in restoring non-vital teeth, but the spectrum of recommended uses should generally be reconsidered and expanded, given our finding of high survival and success rates for IPS e.max ceramics, even for uses not currently recommended by the manufacturer.

Retrospective Multicenter Study

Abstract Background Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP; EDGE) is an alternative to enteroscopy- and laparoscopy-assisted ERCP in patients with Roux-en-Y gastric bypass anatomy. Although short-term results are promising, the long-term outcomes are not known. The aims of this study were: (1) to determine the rates of long-term adverse events after EDGE, with a focus on rates of persistent gastrogastric or jejunogastric fistula; (2) to identify predictors of persistent fistula; (3) to assess the outcomes of endoscopic closure when persistent fistula is encountered. Methods This was a multicenter retrospective study involving 13 centers between February 2015 and March 2019. Adverse events were defined according to the ASGE lexicon. Persistent fistula was defined as an upper gastrointestinal series or esophagogastroduodenoscopy showing evidence of fistula. Results 178 patients (mean age 58 years, 79 % women) underwent EDGE. Technical success was achieved in 98 % of cases (175/178), with a mean procedure time of 92 minutes. Periprocedural adverse events occurred in 28 patients (15.7 %; mild 10.1 %, moderate 3.4 %, severe 2.2 %). The four severe adverse events were managed laparoscopically. Persistent fistula was diagnosed in 10 % of those sent for objective testing (9/90). Following identification of a fistula, 5 /9 patients underwent endoscopic closure procedures, which were successful in all cases. Conclusions The EDGE procedure is associated with high clinical success rates and an acceptable risk profile. Persistent fistulas after lumen-apposing stent removal are uncommon, but objective testing is recommended to identify their presence. When persistent fistulas are identified, endoscopic treatment is warranted, and should be successful in closing the fistula.
