Clinical outcome of a short-term psychotherapeutic intervention for the treatment of dental phobia
No full textObjective: Anxiety before receiving dental treatment is widespread. The aim of this investigation was to evaluate the effect of a brief psychologic treatment on adherence to the dental treatment regimen in patients with dental phobia. Method and Materials: Dental phobic patients (n = 160) received 3 sessions of cognitive behavioral therapy that consisted of stress management training and exposure to phobic stimuli. The outcome was determined in terms of 3 subsequent dental visits. Results: Participating patients had not visited a dental clinician for an average of 6 years. Comparison of patients who completed the psychologic treatment with those who dropped out showed that 68% of the former but also 52% of the latter adhered to the subsequent dental treatment regimen. The number of psychologic treatment sessions correlated significantly and positively with anxiety level before treatment. Conclusion: Short-term psychologic therapy of 3 sessions results in a success rate of 70% to adherence to dental treatment among dental phobic patients. Duration of avoidance of anxiety before treatment was not related to success in completing the trial. Nevertheless, the more intense the patient's phobia, the more psychotherapeutic sessions were necessary. (Quintessence Int 2007;38; E589-E596)
Osseoperception: active tactile sensibility of osseointegrated dental implants
No full textThe phenomenon of developing a certain tactile sensibility through osseointegrated dental implants is called osseoperception. Active tactile sensibility can be tested by having the subject bite on test bodies. The aim of the study was to describe the active tactile sensibility of single-tooth implants based on the 50% value and the slope of the sensibility curve at the 50% value
Are there differences in the changes in oral-health-related quality of life (OHRQoL) depending on the type (rigidity) of prosthetic treatment?
No full textOBJECTIVE
This prospective pilot study investigated differences in changes in oral-health-related quality of life (OHRQoL) depending on the prosthetic treatment type (rigidity).
METHOD AND MATERIALS
Sixty participants seeking prosthetic treatment were included. The following data were collected before (T1) and 4 weeks after completion of prosthetic treatment (T2): OHRQoL (OHIP-G14) and dental status, categorized in terms of rigidity of the denture as fixed dental prosthesis (FDP, maximal rigidity), removable partial denture prosthesis (RPD, medium rigidity), or complete dentures (CDs, minimal rigidity). After prosthetic treatment, there were three groups of 20 participants: group 1, change in dental status to less rigid; group 2, equally rigid; group 3, more rigid restorations. Data were evaluated using nonparametric statistical test methods and power analysis. The minimally important difference (MID) of two OHIP-G14 units was determined to be clinically relevant.
RESULTS
At T1, 20 participants had FDP, 18 RPD, and 22 CD; at T2, 10 had FDP, 37 RPD, and 13 CD. Overall, average OHIP-G14 values improved clinically relevantly and statistically significantly (P < .001) with treatment. OHRQoL improved more in group 3, with a median of 8 (IQR 14.75; P = .002), than in group 2, with 2.5 (IQR 9.5; P = .033), or group 1, with 4.5 (IQR 16.5; P = .116). Applying MID, all groups improved clinically significantly. Compared to groups 1 and 2, group 3 improved clinically more significantly.
CONCLUSION
OHRQoL improved with prosthetic treatment. A patient-customized treatment regime seems as important as prosthesis type (rigidity)
[Management of a failing implant supporting a bar-retained maxillary overdenture by means of alveolar ridge augmentation. Implant loss and reimplantation]
No full textThis case report presents the treatment sequence of a 56 years old patient after he developed periimplantitis at the implant in position of tooth 22. This implant was integrated in an overdenture reconstruction connected to a soldered screw retained gold bar. The entire 2-stage procedure of implant explantation, simultaneous bone augmentation and new implant placement is documented. The onlay-graft was performed by means of the Transfer-Ring-Control System (Meisinger). The existing gold bar could be resoldered and adapted to the new implant. Accordingly the overdenture was relined and the female retainer mounted. The treatment period covered almost one year
Langzeitergebnisse regenerativ-chirurgischer Parodontaltherapie : Eine retrospektive Analyse
Full text linkEine große Zahl randomisierter klinischer Studien belegt die Effektivität einer regenerativ-chirurgischen Parododontaltherapie bei Patienten mit vertikalen Knochen-defekten. Allerdings wurden die meisten Studien in universitären Zentren durchgeführt, hatten ein selektiertes Patientengut, kleine Fallzahlen und erstreckten sich zumeist nur über 12 Monate. Das Ziel der vorliegenden Arbeit war es daher zu überprüfen, ob die Ergebnisse auf die Situation in einer spezialisierten Praxis übertragen werden können und die Langzeitergebnisse der Therapie zu analysieren. Insgesamt 1008 vertikale parodontale Knochendefekte bei 176 Patienten, die zuvor mit deproteinisiertem bovinen Knochenmineral mit oder ohne einer Kollagenmembran oder Schmelzmatrixproteinen behandelt worden waren, wurden retrospektiv analysiert. Die Defekte wurden als 1- und 2-wandig und als flach (≤ 6 mm), moderat (> 6 und < 11 mm) oder tief (≥ 11 mm) klassifiziert. Veränderungen des mittleren radiologischen Knochen-niveaus und der mittleren Sondierungstiefen wurden nach 1 Jahr, nach 2 - 4 und nach 5 - 10 Jahren untersucht. Die statistische Auswertung wurde sowohl auf Defekt- als auch auf Patientenebene durchgeführt. Nach einem Jahr betrug der mittlere radiologische Knochengewinn 3,8 mm und dieser blieb bis zu 10 Jahre stabil. Tiefe und moderate Defekte zeigten eine höhere Defektauffüllung als flache Defekte (53,3 %, 49,2 %, 42,9 %). Die mittleren initialen Sondierungstiefen von 5,8 mm waren nach einem Jahr auf 3,4 mm reduziert und blieben auch weiterhin flach. Die Zahnverlustrate betrug 2,6 %, hing von der intitialen Defekttiefe ab (flach: 2,2 %, moderat: 1,9 %, tief: 6,6 %) und die Zahnverluste hatten zumeist eine endodontische Ursache. Innerhalb der Limitationen eines retrospektiven Studiendesigns, belegen die Ergebnisse, dass eine regenerativ-chirurgische Parodontaltherapie mit deproteinisiertem bovinem Knochenmineral mit oder ohne Kollagenmembran oder Schmelzmatrixproteinen zu einer langfristigen Defektreduktion und Zahnerhalt bis zu 10 Jahren führen konnte. Bei guter Mundhygiene und Compliance der Patienten können parodontal stark kompromittierte Zähne erfolgreich behandelt und mit guter Langzeitprognose erhalten werden. Eine Übertragbarkeit der in randomisierten klinischen Studien erreichten Ergebnisse auf eine parodontologische Praxis ist gegeben und die große Fallzahl belegt die Effizienz dieser Methode
Performance and marginal bone level alteration around immediately loaded narrow-diameter implants. A prospective clinical study: Results after 1 year.
No full textOBJECTIVE
The aim of the present prospective clinical study was to assess the survival rate and the radiologic crestal bone level alteration around four interforaminal immediately loaded narrow-diameter implants (NDIs) in the edentulous mandible.
METHOD AND MATERIALS
A total of 20 participants received each 4 NDIs (MDI, 3M Espe; diameter 1.8 mm, length 13 or 15 mm) in the edentulous mandible. Immediate loading was performed if insertion torque was 35 Ncm or higher. The implants were loaded the same day by converting the existing full denture into an implant overdenture. Follow-up visits were performed five times (baseline to 52 weeks). Standardized radiographs were taken at baseline and 12, 26, and 52 weeks post-loading. Clinical parameters (Plaque Index, probing depth, bleeding on probing) were assessed. The nonparametric ANOVA test was used to assess crestal bone level changes.
RESULTS
In all 20 patients the healing of the total 80 implants was uneventful and no implant was lost. Sixty-eight (85%) implants were loaded immediately. All clinical parameters showed healthy, stable, and well-maintained peri-implant soft tissue conditions. The mean (± standard deviation) radiographic bone loss after 1 year was 0.78 (± 0.64) mm.
CONCLUSION
According to the 1-year results of this prospective clinical study, NDIs seem to be a reliable alternative to support prostheses in edentulous patients with a reduced horizontal mandibular bone volume
