This document discusses different methods for gaining space during orthodontic treatment, including arch expansion, interproximal reduction, molar distalization, and selective extractions. It provides examples of various arch expansion devices like hyrax expanders. Interproximal reduction involves removing enamel to create space. Molar distalization uses appliances like frog pliers to distalize molars. Extractions may be done for premolars or less commonly second molars. Case examples demonstrate using these techniques to correct malocclusions.

Fabrication of functional complete dentures for edentulous patients who have undergone hemimandibulectomy is a very arduous and demanding endeavor.
The most challenging situation encountered during this procedure is the deviation of the mandible to the resected side. The deviation of the mandible to the resected side is directly proportional to the loss of tissues in the area hemi-mandibulectomy has been performed.
In cases with Cantor and Curtis classes II, III, IV, and V, guide flange prosthesis would be a treatment modality. For guide flange prosthesis to be effective, the sufficient number of posterior teeth that are periodontally sound should be present in the opposite arch.
In patients where reconstruction is not done after resection of the mandible, scar tissue formation occurs over a period of time that stiffens the tissues and worsens prosthetic rehabilitation, leading to compromised treatment planning.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

11. GAINING SPACE BY INTERPROXIMAL REDUCTION
• Interproximal reduction is a procedure to create space for
crowding and increase stability by flattening curved contact
surfaces.
• The enamel is removed by using either:
• a fine dental bur
• a disc in a dental handpiece (drill) or
• by hand with an abrasive strip
12. Enamel reduction by dental bur

15. maximum of 0.5 mm interproximal reduction
per contact is recommended. Therefore, a total of
2.5 mm of tooth-size reduction is possible from
cuspid to cuspid
16. • Decision to do interproximal reduction is based on the
model analysis concerning the overall size
discrepancy.
• It could also be added up with a Bolton analysis
17.

19. GAINING SPACE BY MOLAR DISTALIZATION
• An 11-year-old girl was referred to our clinic for
orthodontic treatment with a chief complaint of
protruding upper anterior teeth and irregular
upper and lower
• With class1 divission 1 mallocclusion
22. TREATMENT OBJECTIVES
• The treatment objectives, based on the clinical examination and the
cephalometric analysis, were to
• 1. Distalize the maxillary molars to establish a well-intercuspated bilateral
Class I molar and canine relationship.
• 2. Retract the upper incisors for overjet reduction.
• 3. Ideally align the fully erupted lower and upper permanent teeth.
23. Occlusal views of the Frog Appliance. A, During activation; B, on
the dental cast and immediately after the cementation
24. Upper occlusal view of the patient immediately after the distalization (A), and intraoral photographs after
cutting of the anchor wires of premolars (B-D) (after 4 months of distalization)
25. Lateral cephalometric and panoramic radiographs of the case
taken immediately after the distalization
26. Facial and intraoral photographs of the case at the end of the fixed orthodontic treatment (age 12
years 4 months).
40. As this case illustrates, it may be advantageous to
remove second molars instead of premolars in
selected patients who cannot be adequately
treated without extractions. Second molar
extraction can create sufficient space in the
posterior segments of patients with crowded
arches, providing good long-term facial and dental
esthetics. In addition, it is a relatively simple
procedure that leaves the patient with the
maximum possible number of permanent teeth.

53. Closing the remaining extraction space came from
burning anchorage and moving upper molars mesially.
Case finished with aclass II molar relation, which was
anticipated.
54.
55.
56. The dental panoramic tomogram confirmed the
presence of all permanent teeth, including
developing third molars.
The first molars were all restored or carious, and
their long-term prognosis was considered to be poor.

114. Mandibular incisor extraction can be an effective treatment
option in border line cases with mild crowding in lower arch. In
patients with moderate crowding and without excessive
mandibular tooth mass, interproximal reduction may be a better
alternative. Formation of open gingival embrasures or black
triangles is a common side effect of mandibular incisor
extraction. Minimal alteration of mandibular arch form is key for
success and stable results.
