  • a prospective study on the clinical effectiveness of the Stainless Steel Crown herbst appliance
    Progress in Orthodontics, 2012
    Co-Authors: Dalia Latkauskiene, Gundega Jakobsone, James A Mcnamara
    Abstract:

    Abstract Objectives To evaluate the clinical performance of the Stainless Steel Crown Herbst (cHerbst) used as a single appliance for a single phase therapy. Materials and methods A total of 180 consecutive Class II patients were treated with cHerbst for one year and followed up one year after the end of treatment. Results Class I relationship was achieved in all 175 patients who finished the functional phase of treatment, 58 patients continued treatment with fixed appliances while 21 patients (12%) showed relapse. Seventy two patients (41.1%) obtained and maintained stable Class I relationship one year after treatment with the cHerbst appliance used as a single appliance. Altogether 46 episodes of appliance breakages were observed and most of them could be repaired at the chair side. Patients’ questionnaire revealed that in general the appliance was easy to tolerate and did not cause esthetic or functional problems. Conclusions The Crown Herbst appliance is a viable therapeutical option in patients with Class II malocclusions and it is characterized by low complication rate along with good patient compliance.

  • a cephalometric comparison of treatment with the twin block and Stainless Steel Crown herbst appliances followed by fixed appliance therapy
    American Journal of Orthodontics and Dentofacial Orthopedics, 2004
    Co-Authors: Abbie T Schaefer, James A Mcnamara, Lorenzo Franchi, Tiziano Baccetti
    Abstract:

    This study compared the effects of 2 treatment protocols for correcting Class II disharmony. The first phase of treatment consisted of functional jaw orthopedics with either the Twin-block or the Stainless-Steel Crown Herbst appliance; the second phase consisted of comprehensive fixed-appliance therapy in both protocols. Each of the 2 samples comprised 28 consecutively treated Class II patients. The mean age at the start of treatment was approximately 12 years, and the mean age at the end of the treatment was approximately 14.5 years in both groups. The duration of the treatment phase with the functional appliance was approximately 13 months, and the duration of fixed-appliance therapy was approximately 15 months in both groups. The sex distribution was identical in the 2 groups. Lateral cephalograms were analyzed at the start of treatment (T1) and at the end of the overall treatment protocol (T2). Nonparametric statistics were used for comparisons of starting forms and of the T1-T2 changes between the 2 treatment groups. The Stainless-Steel Crown Herbst appliance and the Twin-block appliance produced very similar therapeutic modifications in Class II patients, although the Twin-block group exhibited almost 2 mm greater correction of the maxillomandibular differential than did the Crown Herbst group. The treatment effects of both protocols led to a normalization of the dentoskeletal parameters at the end of the overall treatment period. Twin-block therapy also induced a greater increase in the height of the mandibular ramus (posterior facial height). Overall, only minor differences were detected in the treatment and posttreatment effects of a compliance-free (Crown Herbst) and a noncompliance-free (Twin-block) appliance for correcting Class II disharmony.

  • success rate of formocresol pulpotomy in primary molars restored with Stainless Steel Crown vs amalga
    Pediatric Dentistry, 2002
    Co-Authors: Gideon Holan, Anna B Fuks, Nirit Ketlz
    Abstract:

    Purpose: The purpose of this retrospective study was to compare the success rates of formocresol pulpotomy in primary molars restored with Stainless Steel Crowns (SSC) to those restored with amalgam (AM). Methods: Radiographs of pulpotomized primary molars restored with SSC or AM in the principal author’s pediatric dentist practice were evaluated and defined as a “failure” when one or more of the following signs were present: internal (IR) or external (ER) root resorption and periapical (PR) or inter-radicular (IRR) radiolucency. Pulp canal obliteration was not regarded as failure. Three hundred and forty-one molars were available for follow-up evaluations ranging from 6 to 103 months. Results: Forty-seven (14%) teeth were defined as “failure,” with a rate of 13% (36/287) for teeth restored with SSC and 20% (11/54) for AM. This difference was not statistically significant (P>0.1). Failure rates of 2 surfaces AM was 23% (7/30), much higher than that of one surface AM (10%, 2/20). Most of the failed teeth presented more than one pathologic finding, with IR being the most frequently observed (36%), followed by ER (31%), IRR (22%) and PR (11%). Pulp canal obliteration was detected in 80% of the teeth, with similar rates in both groups. Failures were observed initially after a mean follow-up of 27 and 29 months in teeth restored with AM and SSC, respectively. Conclusions: Pulpotomized primary molars can be successfully restored with one surface amalgam if their natural exfoliation is expected within not more than two years.(Pediatr Dent 24:212-216, 2002)

  • ferric sulfate versus dilute formocresol in pulpotomized primary molars long term follow up
    Pediatric Dentistry, 1997
    Co-Authors: Anna B Fuks, Gideon Holan, J M Davis, E Eidelman
    Abstract:

    The aim of this study was to compare the effect of ferric sulfate (FS) to that of dilute formocresol (DFC) as pulp dressing agents in pulpotomized primary molars. Ninety-six primary molars in 72 children were treated by a conventional pulpotomy technique. Fifty-eight teeth were treated by a FS solution for 15 sec, rinsed, and covered by zinc oxide-eugenol paste (ZOE). In another 38 teeth, a cotton pellet moistened with 20% DFC was placed for 5 min, removed, and the pulp stumps were covered by ZOE paste. The teeth of both groups were sealed by a second layer of intermediate restorative material (IRM) and restored with a Stainless Steel Crown. This is a report of the clinical and radiographic examination of 55 teeth dressed with FS and 37 teeth fixed with DFC, that have been treated 6 to 34 months previously (mean 20.5 months). Four teeth were excluded from the study due to failure of the patient to present for recall. Success rates of 92.7% for the FS, and of 83.8% for the DFC were not significantly different. Four teeth (7.2%) of the FS group and two (5.4%) of the DFC group presented internal resorption. Inter-radicular radiolucencies were observed in two teeth of the FS group and three teeth of the DFC group. The latter also presented periapical lesions. Success rates of both groups were similar to those of previous studies utilizing the traditional Buckley's formocresol.
