Abstract
Palatal implants have been used to establ ish stat ionary anchorage. The stability of a palatal implant
for distalization of molars bodily and for anchorage maintenance was assessed. The implant was a stepped screw
titanium (4.5 mm diameter x 8.5 mm length), and it was placed in the palatal region. A surgical template containing a
metal drill housing was prepared. Angulation of the drill housing was controlled according to the radiologic tracing
of the maxilla transferred to a plaster cast section in the paramedian plane. The implant was placed using a
noninvasive technique and left transmucosally to facilitate the surgical procedure and to reduce the number of
operations. The paramedian region was selected (1) to avoid the connective tissues of the palatine suture and (2)
because it is considered to be a suitable host site for implant placement. After three months of healing, the
implant was osseointegrated and orthodontic treatment was initiated. The results showed that the molars were
distalized bodily at five months, and no anchorage loss was observed. At the end of the treatment, the smile was
improved, and an ideal Class I molar and canine relationship, an ideal overbite, and an ideal overjet were all
achieved. In conclusion, palatal implants can be used effectively for anchorage maintenance and in space-gaining
procedures. Use of a three-dimensional surgical template eliminated implant placement errors, reduced chair time,
minimized trauma to the tissues, and enhanced osseointegration. This method can be used effectively to achieve
distalization of molars bodily without anchorage loss.
