- Background: Costs for single-implant treatment are mostly described for the initial treatment. Information on the additional cost related to aftercare is scarce. Objective: To make an estimation of complication costs of single implants in periodontally healthy patients after 16-22years and to compare costs for various prosthetic designs. Materials and methods: Patients with a single implant were recalled for a clinical examination and file investigation. Prosthetic designs included single-tooth (ST) and CeraOne (CO) abutments supporting a porcelain-fused-to-metal (PFM), all-ceramic (CER), or gold-acrylic (ACR) crown. Costs related to failures or technical, biologic, and aesthetic complications were retrieved from patient's records. Total and yearly additional complication costs were calculated as a percentage relative to the initial cost. Chair time needed to solve the complication was recorded and prosthetic designs were compared by Kruskal-Wallis tests. Results: Fifty patients with 59 surviving implants were clinically investigated. Additional complication costs after a mean follow-up of 18.5years amounted to 23% (range 0-110%) of the initial treatment cost. In total, 39% of implants presented with no costs, whereas 22% and 8% encountered additional costs over 50% and 75%, respectively. In 2%, the complication costs exceeded the initial cost. The mean yearly additional cost was 1.2% (range 0-6%) and mean complication time per implant was 67min (range 0-345min). Differences between prosthetic designs (CO, ST-PFM, ST-ACR) were statistically significant for total cost (P=0.011), yearly cost (P=0.023), and time (P=0.023). Pairwise comparison revealed significant lower costs for CO compared with ST-ACR reconstructions. Conclusion: Patients should be informed about additional costs related to complications with single implants. The mean additional cost spent on complications was almost one-quarter of the initial treatment price. A majority of implants presented with lower additional costs, whereas the highest complication costs were related to a smaller group with 22% of the implants needing more than half of the initial cost for complication management. Expenses were significantly different for various prosthetic designs.

A pilot assessment tool of the need for oral health care and cost prediction in institutionalized elderly people
- 2017
-
In: International Journal of Dental Hygiene. - : Blackwell Munksgaard. - 1601-5029 .- 1601-5037. ; 15:4, s. 306-312

Journal article (peer-reviewed)abstract
- OBJECTIVE: To assess the dental treatment backlog and associated costs among institutionalized elderly people using a novel composite index, called the oral health index. BACKGROUND: Despite numerous reports about oral health of old individuals, there is still lack of a systematic and practical method to estimate their treatment need covering all relevant aspects of oral health. In addition, little has been published on associated treatment costs and prediction of such costs. MATERIALS AND METHODS: An observational study was performed on 143 dentate institutionalized elderly people, whereby several clinical parameters were registered. The collected data were included in the oral health index representing the need for oral health care. This covered the number of caries lesions, number of residual roots, periodontal health condition, plaque score and denture condition with a final score of 0-9. To investigate the validity of the index, the treatment costs were estimated using the measured clinical parameters and later compared with the actual expenditure of the patients for the following 2 years. RESULTS: The average score of the index was 4.6 (SD 1.4) with 65.1% of the individuals having a score between 3 and 6 and 27.3% having a score of 6 and more, exhibiting medium and high need for oral health care, respectively. Only 30% of the patients underwent all the indicated treatments. The major reason of non-completion of the treatment was patient's refusal. From the fully treated group, 61.5% of the subjects actually spent within the predicted range while 38.5% of them spent more than estimated. The underestimation was related to yearly calculus removals leading to repeated calculation of the same costs and newly emerging dental problems (33% developed new caries and 20% was confronted with tooth fracture within the 2-year period). CONCLUSION: The novel index can be helpful to determine oral treatment needs and associated costs. Further research is needed to extend the clinical applicability of the index.

Effects of root surface debridement using Er:YAG Laser versus ultrasonic scaling : a SEM study
- 2014
-
In: International Journal of Dental Hygiene. - : John Wiley & Sons. - 1601-5029 .- 1601-5037. ; 12:4, s. 273-284
-
Journal article (peer-reviewed)abstract
- Objective: Despite promising results of Er:YAG laser in periodontal debridement, to date there is no consensus about the ideal settings for clinical use. This experimental clinical trial aimed to determine the effects of debridement using Er:YAG laser and to compare with ultrasonic treatment. Materials and methods: Sixty-four teeth were divided into two in vivo and in vitro subgroups. Each tooth received ultrasonic treatment on one side and Er:YAG laser debridement at either 60, 100, 160 or 250mJpulse(-1) and at 10Hz on the other side on a random basis. All samples were morphologically analyzed afterwards under scanning electron microscope for surface changes and dentinal tubules exposure. Treatment duration (d) was also recorded. Results: Laser debridement produced an irregular, rough and flaky surface free of carbonization or meltdown while ultrasound produced a relatively smoother surface. The number of exposed dentinal tubules (n) followed an energy-dependent trend. The number of exposed tubules among the in vivo laser groups was n60mJ=n100mJd100mJ>dUltrasound=d160mJ>d250mJ (P0.046), while for the in vitro groups it was d60mJ>d100mJ=dUltrasound=d160mJ>d250mJ (P0.046). Conclusions: Due to excessive treatment duration and surface damage, Er:YAG laser debridement at 60 and 250mJpulse(-1), respectively, is not appropriate for clinical use. Although laser debridement at 100 and 160mJpulse(-1) seems more suitable for clinical application, compared to ultrasound the former is more time-consuming and the latter is more aggressive. Using a feedback device or lower pulse energies are recommended when using laser in closed field.

An Exploratory Case-Control Study on the Impact of IL-1 Gene Polymorphisms on Early Implant Failure
- 2016
-
In: Clinical Implant Dentistry and Related Research. - : John Wiley & Sons. - 1523-0899 .- 1708-8208. ; 18:2, s. 234-240

Journal article (peer-reviewed)abstract
- Background The association between IL-1 gene polymorphisms and peri-implantitis has been well documented. However, data on the association with early implant failure are scarce. Purpose The objective of this case-control study was to explore the impact of IL-1A (-889), IL-1B (-511), and IL-1B (+3,954) gene polymorphisms on early implant failure in Caucasians Materials and Methods Between September 2004 and August 2007, 461 patients were treated with dental implants at the University Hospital in Ghent, Belgium. Fourteen subjects of this patient group who had experienced one or more early implant failures (within 6 months from implant installation) were recruited as cases. Fourteen controls, matched in terms of age, gender, and smoking habits, with only surviving implants, were selected from the same patient group. Allele and genotype analysis was performed on the basis of a blood sample by Sanger sequencing of polymerase chain reaction products containing the IL-1A (-889), IL-1B (-511), and IL-1B (+3,954) gene polymorphisms Results A significant impact of the IL-1A (-889) T allele (p=.039) and the IL-1B (+3,954) T allele (p=.003) on early implant failure was demonstrated (odds ratios=3.9 and 15.0, respectively). In addition, the genotypic distribution differed significantly between cases and controls for IL-1B (+3,954) (p=.015 ConclusionsThe IL-1B (+3,954) gene polymorphism seems to affect osseointegration. Additional case-control studies in larger patient groups are needed to confirm this observation.

Dental implant register: Summary and consensus statements of group 2. The 5th EAO Consensus Conference 2018
- 2018
-
In: Clinical Oral Implants Research. - : Wiley. - 0905-7161 .- 1600-0501. ; 29:Supplement: 18, s. 157-159
-
Journal article (peer-reviewed)abstract
- Objectives: This publication reports the EAO Workshop group-2 and consensus plenary discussions and statements on a narrative review providing the background and possible facilities and importance of a dental implant register, to allow for a systematic follow-up of the clinical outcome of dental implant treatment in various clinical settings. It should be observed that the format of the review and the subsequent consensus report consciously departs from conventional consensus publications and reports. Material and methods: The publication was a narrative review on the presence and significance of quality registers regarding select medical conditions and procedures. The group discussed and evaluated the publication and made corrections and recommendations to the authors and agreed on the statements and recommendations described in this consensus report. Results: Possible registrations to be included in an implant register were discussed and agreed as a preliminary basis for further development, meaning that additional parameters be included or some be deleted. Conclusions: It was agreed to bring the idea of an implant quality register, including the presented results of discussions and proposals by the group- and plenary sessions, to the EAO Board for further discussion and decision.

Biological aspects: Summary and consensus statements of group 2. The 5th EAO Consensus Conference 2018
- 2018
-
In: Clinical Oral Implants Research. - : Wiley. - 0905-7161 .- 1600-0501. ; 29:Supplement: 18, s. 152-156
-
Journal article (peer-reviewed)abstract
- Objectives: This publication reports the EAO Workshop group-2 discussions and consensus statements which provided the scientific evidence on the influence of biological parameters on implant-related clinical outcomes. Material and methods: The first publication was a systematic review on the biological effects of abutment material on the stability of peri-implant marginal bone levels and the second, a critical narrative review on how peri-implant diagnostic parameters correspond with long-term implant survival and success. The group evaluated the content of both publications, made corrections and recommendations to the authors and agreed on the consensus statements, clinical recommendations and recommendations for future research, which are described in this consensus report. Results: Tested abutment materials can be considered appropriate for clinical use according to the observation period studied (mean 3.5 years). Mean peri-implant bone loss and mean probing pocket depths are not adequate outcomes to study the prevalence of peri-implantitis, while the reporting of frequency distributions is considered more appropriate. Conclusions: Titanium is currently considered the standard of care as abutment material, although other materials may be more suitable for aesthetic locations. Peri-implantitis should be diagnosed through composite evaluations of peri-implant tissue inflammation and assessment of marginal bone loss with different thresholds.
