The article presents a new boneborne and tissue-borne rapid palatal expander called the Haas-inspired miniscrew-assisted maxillary expander (HIMAME). The HIMAME uses metal pads covering the palate and is anchored to the palate with four temporary anchorage devices inserted bicortically. It was used successfully to expand the maxilla of a 17-year-old patient with a transverse deficiency, widening the arch by 4.8mm between the premolars with minimal tipping of the anchor teeth. The HIMAME provides skeletal anchorage which avoids unwanted side effects on teeth seen with traditional rapid palatal expanders.

Abstract: Immediate implant placement has been the acceptable procedure for the past two decades. Perhaps
the most important aspect of any implant surgery in accordance with the successful procedure is implant
surgery and bone to implant contact.The aim of this article is to describe a clinical case in which a fractured
maxillary canine was replaced by an immediately loaded postextraction implant using a simplified technique,
which permits a reduction of the number of implant components and consequently a lower cost of treatment,
while at the same time maintaining acceptable aesthetic and functional outcomes.

Treatment of Extremely Displaced and Impacted Second Premolar in the MandibleAbu-Hussein Muhamad
The mandibular second premolar is one of the most frequently impacted teeth. The recommended treatment is to extract the second primary molar with or without removing the bone along the eruption path, to uncover the tooth surgically and move it into the arch by orthodontic treatment. The purpose of this article is to review the principles of case management of soft tissue impacted second premolars mandibular and to illustrate their potential to respond well to the treatment. Although the scope of treatment may depend on a varying range of factors, this case report demonstrates the inherent potential for good treatment outcome in cases of soft tissue impactions.
Surgery of Labially Impacted Canine & Orthodontic Management – A Case ReportAbu-Hussein Muhamad
Maxillary canines are one of the most common teeth that are impacted among patients seeking orthodontic treatment. Depending on the position of these impacted teeth, various surgical techniques have been employed for their exposure. His primary goal of surgical phase is to provide the means for correct position of orthodontic anchorage. Additionally, the technique used must ensure favorable tissue anatomy that will permit long-term maintenance of periodontal health. In the present case, a labially impacted maxillary left canine was surgically exposed using an apically positioned flap. Orthodontic extrusion was carried out further.

Modern Treatment for Congenitally Missing Teeth : A Multidisciplinary Appro...Abu-Hussein Muhamad
The maxillary lateral incisor is the second most common congenitally absent tooth. There are several treatment options for replacing the missing maxillary lateral incisor, including canine substitution, tooth-supported restoration, or single-tooth implant. Dental implants are an appropriate treatment option for replacing missing maxillary lateral incisor teeth in adolescents when their dental and skeletal development is complete. This case report presents the treatment of a patient with congenitally missing maxillary lateral incisors using dental implants. Finally, the importance of interdisciplinary team treatment planning is emphasized as a requirement for achieving optimal final esthetics
Multidisciplinary Approach in the Rehabilitation of Congenitally Maxillary C...Abu-Hussein Muhamad
Objective: This case report describes the multidisciplinary
approach to treat a congenitally missed maxillary canine, how to
improve patient’s smile using orthodontic fixed appliance, endosseous
dental implant, and porcelain veneer to achieve the treatment results of
function and esthetic.
Materials and procedures: Unilateral agenesis of the permanent
maxillary canines in healthy individuals is extremely rare. This
paper presents the case of a female patient diagnosed with congenital
unilateral agenesis of the permanent maxillary canines as well as
occlusal abnormalities in the form of left-side crossbite. To restore the
proper aesthetics and function, interdisciplinary therapeutic treatment
was implemented. In the case presented in this paper, the aim of
oral rehabilitation was to restore a functional balance by obtaining
proper skeletal relationships, creating optimal occlusal conditions and
obtaining arch continuity.
Conclusion: Interdisciplinary treatment combined of orthodontics,
implant surgery, and prosthodontics was useful to treat a nonsyndromic
oligodontia patient. Especially, with the new strategy, implantanchored
orthodontics, which can facilitate the treatmentand make it
more simply with greater predictability.

Titanium Button With Chain by Watted For Orthodontic Traction of Impacted Ma...Abu-Hussein Muhamad
Abstract: Advances in bonding techniques and materials allow for reliable bracket placement on ectopically positioned teeth. This prospective study evaluates the outcome of forced orthodontic eruption of impacted canine teeth in both palatal and labial positions. Eighty-two impacted maxillary canines in 2200patients were included in the study and were observed for 2006 to 2013 ,in Center for Dentistry research and Aesthetics, Jatt/Israel after exposure. Following exposure by means of a palatal flap or an apically repositioned buccal flap, an orthodontic traction hook, with a Titanium Button with chain by Watted (Dentaurum) attached, was bonded to each impacted tooth using a light cured orthodontic resin cement. A periodontal dressing was placed over the surgical site for a period of time. All teeth were successfully erupted. Complications consisted of: failure of initial bond, at the time of surgery, which required rebonding; premature debonding at the time of pack removal and; debonding of brackets during orthodontic eruption. There was no infection, eruption failure, ankylosis, resorption or periodontal defect (pocket greater than 3 mm) associated with any of the exposed teeth. Forced orthodontic eruption of impacted maxillary canines with a well bonded orthodontic traction hook and ligation chain, used in conjunction with a palatal flap or an apically repositioned labial flap, results in predictable orthodontic eruption with few complications.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

promotes more parallel expansion in the coronal
plane, and increases the potential amount of pala-
tal expansion.27,28
Another important element in preventing re-
lapse of maxillary transverse expansion is the de-
sign of the rapid palatal expander (RPE). The most
popular fixed RPEs with central jackscrews are the
Haas appliance, a tissue-borne device with acrylic
pads contacting the palate, and the Hyrax,* an en-
tirely toothborne metal framework that stands away
from the palate.29 The Hyrax version is popular
because it is easy to clean and fabricate and inter-
feres minimally with speech,30 but it does not pro-
vide the tissue-borne device’s orthopedic compo-
nent of force for control of molar crown tipping.31-34
This article presents a new tissue- and bone-
bone MARPE: the Haas-inspired miniscrew-
assisted maxillary expander (HIMAME).
Appliance Design
The HIMAME is unique in that it uses met-
al pads to cover the palate, rather than acrylic pads
as in the traditional Haas RPE design (Fig. 1). The
metal pads, which are an average 1.5mm thick,
extend from the mesial of the second premolars to
the distal of the first molars (3mm from the gingi-
val margin in this example). The wide extension
and posterior position on the palatal slopes were
designed to apply lateral forces against the pterygo
maxillary buttress—a major source of resistance
to maxillary expansion.35,36 A 10mm jackscrew**
is soldered at the junction of the metal pads.
The HIMAME is connected to the maxilla
with four TADs inserted into the cortical bone of
the palate and nasal floor. The four insertion slots
are placed 1mm from the central slot between the

metal pads, 2mm mesial and distal to the jackscrew.
The HIMAME workflow is completely dig-
ital (Fig. 2). We create digital impressions of the
maxillary and mandibular arches with a CS
3600*** digital intraoral scanner. The stereolitho-
graphic (STL) files and cone-beam computed to-
mography (CBCT) files are then sent to a digital
lab,† where the three-dimensional model is
matched with the CBCT to design the metal pads
and TAD insertion slots. The specific slot locations
are individually calibrated for the selected mini-
screw implants to ensure precise insertion perpen-
dicular to the basal bone, without the need for a
surgical placement guide.

Case Report
A 17-year-old female was referred by her
dentist with “crooked teeth” (Fig. 4). Clinical ex-
amination showed an oval face with a biprotrusive
profile, a mandibular shift to the right, and com-
petent lips. The patient had a Class I canine rela-
tionship on the right side, with the upper canine
out of occlusion, and Class II molar and canine
relationships on the left. A severe upper dental
midline shift to the right, a constricted upper
arch, and severe crowding in both arches were
also observed. The upper right lateral incisor and
upper left central and lateral incisors were in
crossbite. A 21mm upper arch-width discrepancy
was measured between the distal aspects of the
second molars.
The panoramic radiograph revealed the pres-
ence of all permanent teeth. Cephalometric anal-
ysis indicated a skeletal Class III tendency with
bimaxillary protrusion, proclined upper and lower
incisors, and normal facial height (Table 1).
Treatment goals were to achieve Class I mo-
lar and canine relationships, widen the maxillary
arch, correct the dental midlines, create proper
overjet and overbite, and align both arches, all
without negatively affecting facial esthetics.
Some evidence indicates that basal bone can
be widened even in patients who have finished
skeletal maturation.37 Although our patient’s skel-
etal discrepancy could have been treated with a
conventional RPE anchored to the upper first mo-
lars and premolars, we decided against that option
to avoid side effects on the anchor teeth.7,9,10
SARPE was rejected because of its invasiveness,
surgical risks, and cost.38 Since MARPE has been
shown to be effective and reliable in the treatment
of young adults, we proposed this option and ob-
tained informed consent from the patient and her
family.15,17,18

We selected four bicortical miniscrews†† with
a diameter of 2mm, an intraosseous length of 10mm,
a neck length of 3mm, and a total length of 15.8mm.
The TADs were inserted into the palatal bone
1.5mm paramedian to the midpalatal suture, an area
considered ideal for miniscrew placement.39-41
The patient was instructed to follow a strict
oral-hygiene protocol involving a daily .12%
chlorhexidine mouthrinse. Activation of the ex-
pander required two turns per day (one in the morn-
ing and one in the evening) for 12 days. The patient
reported discomfort in the palatal vault and nose
cavity and some difficulty in swallowing on the
first day after HIMAME insertion and activation,
but these effects had lessened by the second day.
Activation was discontinued after 6mm of
expansion (Fig. 5). The metal pads appeared to be
slightly embedded on the left side of the palatal
mucosa, but no signs or symptoms of inflammation
were noted.

One week later, a progress CBCT confirmed
7.52mm of widening in the anterior part of the
suture and 4.16mm in the posterior part (Fig. 6).
Analysis of the digital models indicated increases
of 4.8mm in arch width between the upper first
premolars, 2.6mm in arch width between the upper
first molars, and 5mm in total arch length between
the distal aspects of the second molars (Fig. 7,
Table 2). No change in first-molar inclination was
detected (Fig. 8).
According to our protocol, the HIMAME
was to remain anchored in the palatal bone for 10
months after the end of active expansion. Conven-
tional orthodontic treatment involving four
first-premolar extractions and fixed appliances was
planned.
Discussion
Traditional RPE is generally considered less
efficient and reliable in non-growing patients be-
cause of a greater resistance against the mechan-

and first molars, and secured to acrylic pads with
light-cured composite.32,45 The unique HIMAME
provides several advantages over such designs:
• Using both tissue and bone for anchorage helps
avoid undesirable dental side effects.
• The stiffness of the metal pads increases the
appliance’s rigidity even with minimal thickness
(only 1.5mm), compared with traditional acrylic
designs. Moreover, because the pads retain a resid-
ual force load after activation has ceased, they
contribute to further favorable skeletal changes
during retention.46
• The pads are digitally customized so the sides
fit the palatal vault anatomy, keeping food and oth-
er debris from becoming trapped and thus avoiding
the inflammation usually seen with a Haas RPE.29
• Fabrication requires only x-rays and convention-
al or digital impressions. No expensive or compli-
cated transfer guide is needed, because the cali-
brated insertion slots enable precise TAD insertion
in the selected palatal sites. Once the screws are
tightened, there are no gaps between the TADs and
metal pads, ensuring a secure, stable connection
without compression of the mucosa. No composite
is required for attachment.
• The appliance’s location in the posterior part of
the palate allows the separation force to be distrib-
uted along the entire length of the midpalatal suture,
promoting a more parallel separation of the suture
in an anteroposterior direction.1,32 The posterior
positioning of the TADs helps overcome the skele-
tal resistance to expansion exerted primarily from
the nasomaxillary, zygomaticomaxillary, and
pterygomaxillary buttresses.47-49 Bicortical anchor-
age provides maximum stability of the TADs,
which is essential when heavy forces are applied.25,36
While a traditional RPE can also expand the
maxilla in a 17-year-old patient,37 the MARPE’s
avoidance of stress on the anchor teeth5,7-9 makes
it a more reliable choice for treatment of young
adults.5,16-18,26 Further studies should be conducted
with the HIMAME design to evaluate the effec-
tiveness of this approach across a variety of patient
demographics and to investigate its effect on the
airway and other cranial structures.
