This type of anchorage is critically discussed because of the temporary hygienic impairment of the palate and the uncertain anchoring quality of the button. A\u00a0purely dentally\/periodontally anchored Pendulum\u00a0K appliance was developed, which is exclusively anchored via four occlusal rests. The aims of this pilot study were to examine the suitability of the skeletonized Pendulum\u00a0K for distalization of maxillary molars, and to investigate the quality of this alternative anchoring modality.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Patients and methods<\/jats:title>\n                <jats:p>In all, 10\u00a0patients received skeletonized Pendulum\u00a0K appliances attached to all maxillary premolars for bilateral molar distalization. Supporting anchorage through an acrylic button adjacent to the anterior palate was not used. The pendulum springs were initially activated on both sides with a\u00a0distalization force of 220\u202fcN each and provided with uprighting and toe-in bends. The specific force\/moment system was regularly reactivated intraorally by adjustment of the distal screw.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The study demonstrates the suitability of the skeletonized Pendulum\u00a0K appliance for the distalization of maxillary molars (3.28\u202f\u00b1\u20090.73\u202fmm). Side effects on the molars were slight distal tipping (3.50\u202f\u00b1\u20092.51\u00b0\/PP, 3.00\u202f\u00b1\u20091.41\u00b0\/SN) and mesial inward rotation (average 2.75\u202f\u00b1\u20097.50\u00b0 and 4.50\u202f\u00b1\u200912.77\u00b0). Significant anchorage loss occurred in the form of mesialization of the incisors by 1.40\u202f\u00b1\u20090.82\u202fmm and of the first premolars by 2.28\u202f\u00b1\u20090.85\u202fmm.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The skeletonized Pendulum\u00a0K appliance allows compliance-free upper molar distalization. Exclusively dental\/periodontal anchorage resulted in a\u00a0lower percentage of molar distalization compared to a\u00a0conventional anchoring preparation of the Pendulum\u00a0K with a\u00a0palatal acrylic button. Anchorage loss had a\u00a0comparatively stronger effect on the anchoring premolars but less on the incisors. Typical side effects on the molars such as distal tipping and mesial inward rotation were remarkably low.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00056-021-00280-8","type":"journal-article","created":{"date-parts":[[2021,3,2]],"date-time":"2021-03-02T15:02:42Z","timestamp":1614697362000},"page":"391-402","update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Efficiency of the skeletonized Pendulum\u00a0K appliance for non-compliance maxillary molar distalization"],"prefix":"10.1007","volume":"82","author":[{"given":"Gero Stefan Michael","family":"Kinzinger","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Hourfar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f6rg Alexander","family":"Lisson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,3,2]]},"reference":[{"key":"280_CR1","doi-asserted-by":"publisher","first-page":"520","DOI":"10.1016\/j.ajodo.2005.12.003","volume":"129","author":"F Angelieri","year":"2006","unstructured":"Angelieri\u00a0F, Almeida\u00a0RR, Almeida\u00a0MR, Fuziy\u00a0A (2006) Dentoalveolar and skeletal changes associated with the pendulum appliance followed by fixed orthodontic treatment.
