Vor der Anschaffung
neuer Behandlungs-
Instrumente gilt es
stets sorgfältig abzuwägen,
für welches
Produkt man sich
entscheidet. Die Entscheidung
ist umso sorgfältiger
zu prüfen, je höher die Investition
dafür ausfällt.
In meinem Fall ging es vor
drei Jahren um die Frage, welche
Hand-/Winkelstücke anzuschaff
en waren. In die Entscheidungsfi
ndung fl ossen mehrere
Faktoren ein. Zum einen ist hier
meine persönliche Erfahrung mit
Produkten verschiedener Hersteller
zu nennen. Ein weiterer Punkt
ist die Qualität der Produkte bzw.
deren Langlebigkeit/Serviceanfälligkeit
.Desweiteren ist „Made
in Germany“ ein wichtiges Kriterium
für mich.
Die Entscheidung fi el schlussendlich
auf Produkte des Herstellers
KaVo, da hier alle für mich
relevanten Punkte positiv ausfi elen,
speziell auf Instrumente der
mittlerweile „Master Series“ genannten
Linie.
Sie bestechen durch extreme
Laufruhe, geringes Arbeitsgeräusch
und eine sehr gute
Arbeitsfeldausleuchtung. Die
Durchzugsleistung bei verschiedenen
Drehzahlen und Anpreßdrücken
ist ebenfalls
hervorragend. Ergonomisch
geformt sind die Instrumente
der „Master Series“ ohnehin,
auch hier sind sie schwer
zu übertreff en.
Andere Vorteile bemerkt
man erst später - so habe ich in
den vergangen drei Jahren keinen
Tag Ausfall zu beklagen. Eine
gute Pfl ege, wie z.B. durch die
QuattroCare ist hierfür natürlich
Voraussetzung. Daher hat sich für
mich die Entscheidung für Instrumente
der KaVo „Master Series“
als hervorragende Wahl bewiesen.
Das Zitat von Henry Royce
„Quality exists, when the price is
long forgotten“ hat sich auch für
mich bestätigt.

Seit einiger Zeit arbeite ich in meiner
Zahnarztpraxis mit dem KaVo Comfortdrive-
Instrument, einer neuen
Schnellläufergeneration mit integriertem,
kollektorlosem Antriebsmotor. Äußerlich erinnert
das Comfortdrive an die Gentlepower-
Instrumente. Die Oberfläche ist durch die spespezielle
Plasmatec-Beschichtung hygienisch
glatt und dennoch sehr griffig. Durch die robuste
Beschichtung sieht das Instrument
selbst nach häufigem Sterilisieren, Desinfizieren
und intensiver mechanischer Belastung
noch immer neuwertig aus.

Noise level measurements of the air noise during drilling and grinding on the fresh isolated temporal bone

Paulsen K, Vietor K
Laryngol Rhinol Otol (Stuttg). , 3/29/2010
Aerial sound measurements with different drilling instruments were performed during dry running and preparations of the bone. Registered were the values of the small drilling instruments Sirona, Dentatus-Air, and Electro-Torque-Ritter. Also tested were the KaVo-Technique-machine, the Hall-machine, the Air-Orbit-turbine, and the Sirona-turbine. During dry running most of them already reached the allowed marginal value of noise nuisance for the ear of 85 dB (A) at a distance of 35 cm. Only the Air-Orbit-machine showed a slightly lower value of 80 dB (A). The level increases with the used handpieces. Normal handpieces 1:1 exert only a minimal influence, gear handpieces 2:1, however, markedly increase the level. The verticity is of no importance in the range of normal rotations between 10,000 r/min. and 80,000 r/min. Only rotations in the lower frequency range of 2,000 r/min. markedly decrease the noise level. During bone drilling, the kind and size of the drilling bit have an influence on the intensity of the noise level. Quadruple wing milling cutters create a very high noise level (at a distance of 15 cm still above 110 dB [A!]), big rose cutters (R 16) create noise levels of 95 dB (A) and above, and only diamond round bits create less noise (approximately 88 db [A]). Small drilling bits make such a faint noise, that it is overroared by the drilling instrument. The turbines create only slightly higher levels than during dry running. Larger drilling bits cannot be employed here on principle. Wing milling cutters can lead to persistent damages of the inner ear. The frequent use of dental drilling instruments for bone preparations can also lead to a hearing loss of the operator in the long run.

Noise level in dental laboratory practice

Sun J, Yao JJ, Tan Y, Zhang FQ
Shanghai Kou Qiang Yi Xue, 12/1/2009
PURPOSE: Dental technicians are exposed to different noises. The aim of this study was to determine the noise level produced by different dental laboratory handpieces and special equipments in one dental lab. METHODS: The noise level produced by two dental laboratory handpieces(Kavo K9, NSK Vmax) was measured at distance of 15cm, 30cm and 45cm in free-running and different working conditions. Additionally, the noise level produced by some dental laboratory equipments and procedures were also measured both near the technician's ear and 1.5 meters away. The noise level was determined using a precious sound level meter. RESULTS: The mean value of noise level of the two dental laboratory handpieces measured at all distances and in all conditions was between 61 to 83 dB. The noise level produced by some dental laboratory equipments were much higher, with high-speed metal cutting, steam cleaning and power pillo trimmer exceeding 90dB. Noise level inside the denture fabrication room was between 65 to 83 dB. CONCLUSIONS: The noise level in the dental laboratory is considered to be a potential risk causing hearing loss. Regular audiometry checking up should be carried out among the dental technicians and ear protectors must be used during work.

PURPOSE: Modern implant dentistry requires the application of torque during various treatment steps. This study investigated seven different surgical motors for the accuracy of the applied torque and their reliability. MATERIALS AND METHODS: The following surgical motors were evaluated: Chiropro 980 (Bienair), INTRAsurg 300 and INTRAsurg 500 (KaVo), Osseocare (Nobel Biocare), Surgic XT (NSK), Elcomed SA-200 C (W and H), and Osseo System (XO Dentalcare). The torque was measured during typical surgical and prosthetic procedures using a special load transfer mechanism for a torque gauge. For each setting, 30 measurements were made and means were calculated. RESULTS: The highest percentage shortfall was 20.5% at a set torque of 11.4 Ncm (absolute deviation of -2.4 Ncm). The highest percentage by which a torque was exceeded was 54.6% (absolute deviation of 5.5 Ncm). The lowest value for absolute shortfall was found to be -5.6 Ncm at a set torque of 45 Ncm. The highest absolute exceeded was 15 Ncm at a set torque of 40 Ncm. Potentially problematic torque values were identified in the low-torque-value setting, as the implant position may be changed if a machine driver applies excessive torque to the first-stage healing screw. In addition, in the indication of immediate loading in the high-set-torque group, torque values above the critical value of 50 Ncm may be unwittingly applied while working with a set torque of 40 Ncm. CONCLUSION: For most of the clinically relevant torque settings, precise values were

Clin Oral Implants Res. 2008 Dec;19(12):1304-11, 12/1/2008
OBJECTIVES: The purpose of this study was to assess the retrievability of cemented implant crowns using two different removal devices. The influence of five cement types and two cement application techniques was evaluated. METHODS: Forty copings were cast from a CoCr alloy for 40 tapered titanium abutments (5 degrees taper, 4.3 mm diameter, 6 mm height, Camlog, Germany). Twenty copings were modeled as single crowns, whereas 20 copings were modeled with an extension to simulate fixed partial dentures (FPDs). Before cementation, the inner surfaces of the copings were air-abraded (50 mum Al(2)O(3) particles at 2.5 bars), while the abutments were used as delivered with machined surfaces. Copings were cemented with eugenol-free zinc oxide (Freegenol), zinc phosphate (Harvard), glass ionomer (Ketac Cem), polycarboxylate (Durelon) and so-called self-adhesive resin (RelyX Unicem) cement. Cement was applied in a thin film band of 1 or 3 mm to the cervical margin of the inner surface of the copings, respectively. After cementation, specimens were stored in saline solution for 24 h. The Coronaflex and a standardized custom-made removal device were used to remove the copings from the abutments. RESULTS: Using the same cement, no statistically significant influence with regard to the type of restoration (crown/FDP), cement application mode and device was detected (P>0.05). Therefore, data of specimens cemented with the same cement were pooled. Median attempts to remove the copings were: zinc oxide: 3, self-adhesive resin: 3, zinc phosphate: 5, glass ionomer: 16 and polycarboxylate: 58. Four levels of significance (P<0.0001) were found: (1) zinc oxide/self-adhesive resin; (2) zinc phosphate; (3) glass ionomer; and (4) polycarboxylate. CONCLUSIONS: Zinc phosphate and glass ionomer cement might be suitable for a so-called 'semipermanent' (=retrievable) cementation, while polycarboxylate seems to provide the most durable cementation.

This study evaluates the effect on post space debridement in oval-shaped canals of an experimental ultrasonic tip with oval section (Satelec) compared with a circular ultrasonic tip (KaVo). Thirty teeth with an oval-shaped canal were endodontically treated and obturated and then randomly divided into 3 groups (n = 10) according to the procedure used for post space debridement: Satelec tip, Largo #2 drill + KaVo file, and Largo #2 drill + water. Debris and dentin tubules were evaluated by assigning scores to scanning electron microscope post spaces images; lower scores corresponded to fewer debris and higher number of open tubules. The Satelec group showed significantly lower debris and open tubules scores than KaVo group (p < .05) and control group (p < .05), which differed significantly between each other (p < .05). Also the debris and open tubules scores in different post space regions differed significantly among the experimental groups (p < .001). The oval ultrasonic tip resulted in a better post space debridement than a circular ultrasonic tip in oval-shaped canals.
