New materials in oral surgery
No full textCurrently, in the field of dentistry literature, one of most active research topics is clearly related to implants, bone materials, and regenerative strategies for the reconstruction of different oral tissues. Biomaterials and related technologies used with these purposes could only be derived from the integration of the knowledge of different disciplines, which together are skilled in generating innovation and research development, with extensive support of basic sciences and intense international cooperation. The combination of these resources, associated with the greater need for increasingly comprehensive and predictable therapeutic protocols, brings a substantial change in the treatment of oral rehabilitations

No full textAesthetic outcomes and peri-implant health of angled screw retained implant restorations compared with cement retained crowns: Medium term follow-up
No full textSingle tooth implant restorations in the aesthetic area are a demanding challenge. If a complete osseointegration is mandatory, the final result has to result in a higher standard of biomimetic and soft tissue health among natural teeth. This outcome is traditionally pursued by cementing crowns over individualized abutments. However, in recent years, the need for controlling peri-implant health and the preference towards a retrievable solution has led to an increase in screw-retained crowns, which is not always applicable when the implant axis is not ideal. In the aesthetic area, the use of a novel technical solution represented by the angled screw channel (ASC) of the abutment has been proposed in order to match the advantages of the screwed solution with the aesthetic demands. The aim of this study was to compare ASC crowns to cemented crowns (CC) in single implant restorations using the white esthetic score (WES) and pink esthetic score (PES) at the crown delivery and at a follow-up of a minimum of 2 years. Peri-implant health and marginal bone loss (MBL) were also evaluated. The mean follow-up was 44.3 months, with a mean MBL of 0.22 mm in the ASC group and 0.29 mm in the CC group. The total WES/PES score was 16.6 for ASC, compared with 17.3 for CC at baseline, and 16.2 and 17.1, respectively, at follow-up. Both of the groups reached a high WES/PES, and this was maintained over time, without signs of peri-implant diseases or bone loss, regardless of the choice of connection. In conclusion, ASC can be adopted in cases where the implant axis is not ideal, with aesthetic and functional results that are comparable to implants restored by cemented crowns
The frequency of dental anomalies in subjects with cleft lip and palate
No full textObjectives . The purpose of this study was to
investigate dental abnormalities in children
with cleft lip and palate (CLP) in order to identify
the most prevalent anomalies and the teeth
most frequently affected.
Materials and methods . We analyzed orthopanoramics
X-rays (OPT), computed tomography
Dental Scans, clinical records, and dental
casts from 18 consecutive patients (10 boys,
8 girls; mean age 11.2 years, range: 6 to 18),
with CLP (complete or incomplete, mono- or
bilateral) and recorded the presence of the
following anomalies: supernumerary teeth,
agenesis, shape and size anomalies, ectopic
and dystopic eruptions, rotations and retained
teeth.
Results . The most frequent abnormalities
were: agenesis (prevalence: 22.5%), ectopic and
dystopic eruption (19.3%), rotations (17.7%),
shape and size anomalies (16.1%), and retained
teeth (14.5%). The most frequently affected
teeth were the lateral (45.1%) and central
incisors (32.2%), the cuspids (14.5%), and the
second bicuspid (6.4%). Lateral incisors were
usually missing (39.2%) or retained (21.4%),
while central incisors were more often rotated
(50%) or deformed (25%). The cuspids were
ectopic (66.6%) or retained (23%), while the
bicuspids were missing (25%), retained (25%),
or presented alterations in number (25%) or
shape/size (25%)

Early treatment of an ectopic premolar to prevent molar-premolar transposition.
No full textOrthodontic treatment is planned on an individual, case-by-case basis after thoroughly considering the patient's overall facial and dental characteristics, the expected duration of treatment, costs, patient preferences, and the orthodontist's experience. This article reports the treatment of a patient with a maxillary premolar-molar transposition in the permanent dentition that was successfully managed with orthodontic treatment. A girl, aged 10 years 2 months, came for treatment with an ectopic maxillary left premolar. Radiographic analysis indicated a developing complete transposition of the maxillary left premolar. The patient was treated with extraction of the deciduous molar and surgical exposure and ligation of the premolar. Eruption was properly guided, and the correct order of the 2 teeth was restored in the arch. This challenging treatment approach is described in detail, including the mechanics used to align the ectopic premolar. Early treatment can, in many cases, prevent a molar-premolar transposition
