This case report describes the treatment of a 22-year-old female patient with a unilateral cleft lip and palate using distraction osteogenesis (DO) followed by orthognathic surgery. The patient had midface deficiency, a class III malocclusion, and a retrognathic maxilla. Treatment involved using a RED device to perform DO for 7mm of maxillary advancement. This was followed by Lefort I osteotomy, mandibular setback, and genioplasty. Post-treatment, the patient's profile and occlusion were improved with good stability after 2 years. The report concludes that DO is an effective treatment for severe cleft-related maxillary deficiency.

Used in the right conditions, SFOA is highly successful and has a positive impact on the patients psychosocial status.A combined orthodontic and orthognathic surgery approach is accepted as the standard of care for patients who have a severe skeletal jaw discrepancy with facial asymmetry.
But some disadvantages have been recognized.
One drawback is the long presurgical treatment time that typically worsens facial appearance and exacerbates the malocclusion. In some countries, these disadvantages have caused patients to seek plastic surgeons who are willing to perform orthognathic surgeries without collaboration with orthodontists or consideration for the final occlusion.
Recently, to address patient demand and satisfaction, the surgery-first approach was introduced to overcome some disadvantages associated with the conventional surgical orthodontic approach.1991-Brachvogel et al. suggested the potential advantages of a surgery-first approach.
In that article the advantages of post-surgical orthodontics are outlined as follows:
1) Orthodontic movement does not interfere with compensatory biological responses.
2) Dental movements can be based on an already corrected skeletal pattern.
3) Some surgical relapse can be managed during treatment.
2009: Nagasaka et al., popularized SFOA54. Nagasaka et al1 were among the first to actually carry out SFOA using miniplates for post-surgical orthodontic treatment
The 2011 symposium presented the surgery‑first approach and created broader interest in the complete elimination of time‑consuming preoperative orthodontic treatment

Al-Azhar University. Numerous etiologies lie behind mandibular defects including pathologic lesions, trauma related, infectious diseases and congenital defects. At present, the methods to restore mandibular defects can be classified into four basic categories:
1.Autogenous bone grafts in the form of nonvascularized free bone transfer, or vascularized tissue transfer, either pedicled or based on microvascular anastomosis
2. Distraction osteogenesis
3. Alloplastic materials (with or without bone)
4. Tissue engineered grafts
indications and contraindications of rapid maxillary arch expansion,appliances used and effects of rapid maxillary arch expansion/ comparison between rapid and slow expansion
The general indications for SARPE are skeletal maturity, transverse maxillary deficiency, excessive display of buccal corridors when smiling, and anterior crowding.
Modified osteotome sinus floor elevation by using combination PRF membrane, b...Dr. Anuj S Parihar
The osteotome technique is more predictable with simultaneous implant placement when there is less than 5 to 7 mm of pre-existing alveolar bone height beneath sinus. Proper combination of PRF membrane, MFDBA and autogenous bone has been recommended for this situation. The purpose of this article is to describe the proper method and materials which can grow more than 10 mm bone with osteotome technique and grafting materials where the edentulous posterior maxilla radiographically showed less bone between the alveolar crest and sinus floor.
Diagnosis and conservative treatment of skeletaldentalid
A man, aged 28 years 9 months, came for an orthodontic consultation for a skeletal Class III malocclusion
(ANB angle, 3) with a modest asymmetric Class II and Class III molar relationship, complicated by an anterior
crossbite, a deepbite, and 12 mm of asymmetric maxillary crowding. Despite the severity of the malocclusion
(Discrepancy Index, 37), the patient desired noninvasive camouflage treatment. The 3-Ring diagnosis showed
that treatment without extractions or orthognathic surgery was a viable approach. Arch length analysis indicated
that differential interproximal enamel reduction could resolve the crowding and midline discrepancy, but a
miniscrew in the infrazygomatic crest was needed to retract the right buccal segment. The patient accepted
the complex, staged treatment plan with the understanding that it would require about 3.5 years. Fixed appliance
treatment with passive self-ligating brackets, early light short elastics, bite turbos, interproximal enamel
reduction, and infrazygomatic crest retraction opened the vertical dimension of the occlusion, improved the
ANB angle by 2, and achieved excellent alignment, as evidenced by a Cast Radiograph Evaluation score of
28 and a Pink and White dental esthetic score of 3. (

From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

In this patient, the amount of advancement
needed was more than 10 mm; therefore, orthognathic
surgery alone was considered insufficient and unstable.
10mm
45. Suggested retention period for DO 6 to 8 weeks.
Red device 8 weeks of consolidation and 8
weeks of retention with the facemask to prevent
relapse as much as possible.
The 2.4 mm of relapse occurred during the
preoperative orthodontic treatment
1. There was no supplementary appliance for
retention
2. Soft tissue factors and muscle stretch

46. Patient had secondary caries on all 4 maxillary
molars.
To strengthen the anchorage, banding of all 4
molars was planned.
For a patient with multiple missing teeth or not
enough bone in the cranial vault, mini implants
or plates could be considered for the skeletal
anchorage.

47. Louis et al says that relapse rate of OGS increases as the amount of
maxillary advancement increase.

48. According to some studies, the maximum maxillary advancement
achieved by conventional OGS techniques varies, ranging from 5mm -
10mm,depending upon scar contracture.

In our patient, 2.4 mm of relapse, which is about
34% of the total amount of advancement, occurred
during the preoperative orthodontic treatment
According to Hochban et al, Cheung et al, Erbe et al reported that
relapse rate after maxillary advancement of 7.8mm,3.3mm and 4.6mm
was 25%,27% and 40% respectively.

Overcorrection during DO is suggested
Cho and Kyung et al. recommended overcorrection is
of 20% to 30% to minimize relapse.
51. DO is an efficient treatment modality in
severe cleft-related maxillary hypoplasia.
It promotes correction of bone and soft
tissues simultaneously.
Reduces the amount of maxillary movement
during the surgery.
